Question

--Where did you first meet your boyfriend?
---It was in the department store ______ he worked.

A．which

B．that

C．where

D．what

Answer 1

C

考查定语从句和强调句型。补充完整是It was in the department store ______ he worked that I first met my boyfriend.定从 ______ he worked的先行词是the department store，从句缺地点状语，所以选C, where。
