Explanation:
A singular possessive noun is created by adding apostrophe (') to the noun. This is done so in order to show the possession of the noun.
But to use apostrophe to create singular noun possession there are certain grammatical rules.
If a singular noun is ending with 's' then apostrophe can be added after with the word without adding 's' or with adding 's'. Both ways are correct.
In option A, there is no possession shown. And the correct usage of singular possession for option A would be "Mary was dominant among Jesus' disciples.
So, the correct answer is Option A.
