Which sentence contains a nonessential relative clause?
a) the singer, who was very talented, knew the words to the song.
b) the singer remembered the words that were difficult.
c) the singer knew the words to the song that she would sing.
d) the singer who was very talented knew the words to the song.

The correct answer is A) The singer, who was very talented, knew the words to the song.

Explanation:

The clause "who was very talented" is considered to be nonessential for two reasons: 1) it acts as an adjective to the subject "singer", yet, if it were removed, the meaning of the sentence would remain unaltered. 2) it is between commas.

The answer would be, A) The singer, who was very talented, knew the words to the song.
