Đáp án là (C) Were.

Đây là đảo ngữ câu điều kiện loại 2 nhé em.

○ If you were offered that job, would you have to move to another city?
→ Were you to be offered that job, would you have to move to another city?

Cách chuyển đổi là ta bỏ If đi, đưa were ra phía trước, và chuyển động từ chính về dạng to-V.

Một ví dụ khác:

○ If he had enough money, he would buy a new house.
→ Were he to have enough money, he would buy a new house.
