    The most probable answer is probably intended to be a. However, if water vapor is included in the list, it would take the #3 or #4 spot, depending on the ambient temperature and relative humidity. Otherwise, the constituents are listed in decreasing order of abundance in the natural atmosphere.

    c. only carbon dionxide causes the greenhouse effect
