The correct answer is option (C):
Besides Betty and me
The correct answer is "Besides Betty and me." Here's why:
The word "besides" means "in addition to" or "as well as." This is the correct meaning in the context of the sentence, which asks who else was present in addition to Betty and another person.
The pronoun "me" is the correct choice because it is the object of the preposition "besides." Pronouns change form depending on their function in a sentence. When a pronoun is the object of a preposition (like "besides"), the objective case form is used. "Me" is the objective case of "I."
Let's look at why the other options are incorrect:
* "Beside Betty and..." - "Beside" means "next to" or "at the side of." This doesn't fit the meaning of the sentence.
* "Beside Betty and me" - "Beside" isn't the correct preposition; "besides" is.
* "Beside me and Betty" - Again, "beside" is incorrect. While the pronoun "me" is used correctly, the initial word needs to be "besides."
