Answer 2

The correct option for the given sentence is B) but also forgot his mother's birthday.

Explanation

In this sentence the structure 'not only...but (also)' has been used. This structure is used to mean that the doer of an action did both the actions. Option A also looks right, but there is repetition of pronoun 'he' in the clause; so option B is the most appropriate. Hence the complete sentence will be written as shown below:

Carlos not only missed his one-year anniversary with Adrianna but also forgot his mother's birthday.
