What is the underlined clause?

Oh, I just got to that question. The underlined clause is "which we saw at the aquarium last summer."

I believe the answer is "adjective clause" because the clause modifies "movie about whales."

Yes it is correct. I submitted the test and it was correct.

"Which best describes the underlined clause?
I liked the movie about whales, which we saw at the aquarium last summer. "

The answer is "adjective clause."
