Answer:
In my opinion, the answer would be 2. The players who were working at the carwash impressed the customers with their hard work.
Explanation:
I think this would be the answer because a relative clause gives more information about the noun, in this case the players, in the sentence. In addition, a relative clause begins with either who, which, that, and whose, these are called relative pronouns or where, why, when, these are called relative adverbs.
The players= the noun
who= the relative clause
Your correct, It is B
Good Luck!
