Explanation: When we are writing a sentence or a text, we must pay attention to the correct use of punctuation marks, and also the correct placement. One of the most common uses of a comma is to introduce additional information in a sentence, without using parentheses. In the given sentence we should place a comma after the word "Caleb" because the phrase "who are members of the drama club" is giving additional information to the sentence and it should have commas before and after.
