Which one of the following sentences contains an incorrect usage of the singular possessive?

A. Icarus's fate was sealed when he approached the sun.

B. Mary was dominant among Jesus' disciples.

C. The alpha male is often the pack's leader.

D. The north forty has always been my family's land.

I picked A, because the apostrophe should be after the first s and not have two s's. Is this correct?

I agree.

The Correct Answer is (A)..... Believe That!!!

I believe it's A

Yes, you are correct. Sentence A, "Icarus's fate was sealed when he approached the sun," contains an incorrect usage of the singular possessive. According to the standard rules, when creating the possessive form of a singular noun ending in "s," you typically add an apostrophe followed by an "s" (i.e., 's). However, there is an exception when the singular noun already ends in "s" sound; in this case, you only need to add an apostrophe after the existing "s."

Therefore, the correct form of the possessive for Icarus would be "Icarus' fate was sealed when he approached the sun." The additional "s" after the apostrophe is not necessary. This makes Sentence B, C, and D, all correctly using the singular possessive.
