Hello!
I think the answer is B) Zoologist.
I think this is because Dr. Reynolds comes after "the zoologist, Dr. Reynolds." There is a comma after the word zoologist as well, which indicates that the name of the Zoologist is Dr. Reynolds, so Dr. Reynolds identifies the name of the zoologist.
Hope this helps! Best of luck!
I think it’s D. Ocean trenches
