An eclipse occurs at those times when the Moon moves into a position of direct alignment with the Sun and the Earth. There are two basic types of eclipses – lunar and solar. Most people have seen at least one total lunar eclipse, when the full Moon passes through the shadow of the Earth. In this case, the Sun and the Moon are on opposite sides of the Earth. If you observe a lunar eclipse (visible only at night at the time of certain full Moons), you’ll see the bright lunar disk turn dark -- sometimes a coppery red color -- for as long as an hour or more.
But the gentle beauty of a lunar eclipse pales in comparison with the truly awesome spectacle of a total solar eclipse, which occurs when the new Moon passes directly between the Sun and the Earth. In the narrow path of totality swept across the Earth by the Moon’s complete shadow (the umbra), daytime briefly turns to an eerie darkness, and during these few precious minutes the wispy halo of the Sun – the corona –comes into view as the dark disk of the Moon totally obscures the bright Sun. Outside the path of totality, in the Moon’s partial shadow (the penumbra), some portion of the Sun’s bright disk remains visible.
Not all solar eclipses are total. During a partial solar eclipse, only the penumbra touches our planet. The umbra passes either just above the North Pole or just below the South Pole, completely missing the Earth. No total eclipse is visible -- only partial phases can be seen.
A third type of solar eclipse occurs when the Moon's umbra passes across the Earth, but is not quite long enough to touch the surface; the shadow cone diminishes to a point before reaching the Earth. This effect happens when the Moon is farther out in its orbit around the Earth. The Moon appears slightly smaller and is not large enough to completely cover the Sun. When the Moon is centered over the Sun, a ring of sunlight remains visible around the edge. This type of eclipse is called an annular eclipse. Because the Sun is not completely covered by the Moon, the rare and dramatic effects of a total solar eclipse (onset of darkness and view of the corona) are not present at either annular or partial eclipses of the Sun.Source(s): http://www.earthview.com/tutorial/causes.htm

If you think about this, its not hard.
If the moon is between the Earth and the sun and in the right position, we get a solar eclipse (the shadow of the moon touches the Earth's surface). If you are in the umbra of the shadow, it will be a total solar eclipse.
If the Earth is between the moon and the sun and the moon enters the Earth's shadow, you get a lunar eclipse. If the entire moon enters the umbra of the Earth's shadow, it is a total lunar eclipse.

During the time of new Moon, the Moon is between the Sun and the Earth and potentially could cast its shadow onto the Earth. The umbra is the dark inner shadow, while the penumbra is the lighter outer shadow where only part of the Suns light is blocked.
Given that, do you see the answer and understand?

Well, ..., your best option is A. A solar eclipse can only occur at New Moon and the eclipse is total with the moon's umbra passes directly over you.

First is Solar and the second is umbra.

new moon we get solar eclipse
In umbra u get total eclipse otherwise partial eclipse.

The answer is a) which is a total solar eclipse
- ShaulaLv 71 decade ago
(A )would be the correct answer as the moon would be blocking the light from the sun.

Option "A" is correct.
