what is the audio ? it says based on the audio :)
The answer will be D. passive voice
Answer:
The "personal a" is not necessary in that sentence. If you say: "No recuerdo tu nombre" it means "I don't remember your name". If you say "No recuerdo a tu nombre" it is not grammatically correct.
Given that including the "personal a" is grammatically incorrect, then the personal "a" is not necessary.
