Answer:
option D
Step-by-step explanation:
The enharmonic of G# is Ab. An enharmonic is a musical note that is spelled differently from another note, but which is played at the same pitch. In this case, G# and Ab are played at the same pitch, but are spelled differently. G# is spelled with a sharp symbol, while Ab is spelled with a flat symbol. Because of this, G# and Ab are considered to be enharmonics of each other.
