The correct choice in this context is "B) A, the."

When we analyze the first part of the sentence, "Last summer we went on... cruise in the Caribbean," the indefinite article "A" is appropriate before "cruise" because it introduces a non-specific cruise among many possibilities. There’s no prior reference to any specific cruise; thus, we use "A" to indicate that it is one of many.

In the second part, "...the Islands we visited Bermuda and the Bahamas," the definite article "the" is the correct choice before "Islands." This is because "the Islands" refers to a specific group of islands known within the context of the Caribbean and distinguished from others. Here, “the Bahamas” and “Bermuda” are also specific locations that the reader likely recognizes, justifying the use of "the" for both.

In summary, "A" indicates a non-specific cruise, while "the" identifies specific islands that are part of a well-known context, making "B) A, the" the most fitting choice for this sentence.
