The sentence "I did not know that this food was meant only for the staff." is an example of a complex sentence.

Here's why:

A complex sentence is a sentence that contains one independent clause and at least one dependent clause. An independent clause can stand alone as a sentence, while a dependent clause cannot.

In this sentence, "I did not know" is the independent clause, as it can stand alone as a complete thought. "That this food was meant only for the staff" is the dependent clause, as it cannot stand alone and is providing additional information to the independent clause.

Therefore, the answer is c. complex.
