Dear teachers,

1. Unfortunately, our hotel turned out be a(an) _________ distance from the beach.
A. Substantial B. sizeable C. extensive D. considerable

My answer is 'C'. If it is wrong please do tell me why. Thank you so much.

It is not a very good vocabulary question, but the answer is D, which is the only common collocation with 'distance'.
yes i think letter D is the correct one.
