2. Greater than should be used so a is out. --- Left with b and c.
3. greater than that is incorrect because "that" cannot replace "variations". So b is out. --- Left with C.

Hi ritesh,

u r right. OA is C.

In this case "the variation in life spans" needs to be replaced by a pronoun.

The variations in life spans is plural as indicated by all answer choices using "are greater". So singular pronoun that can not be used to replace.
