Correct Option : B
Explanation:
Above sentence is a special because of use of relatively rare "were-subjunctive" verb form that expresses something desired or imagined.
We use subjunctive basically when we want to describe events that are not certain to occur.We normally use subjunctive to explain the event we
- want to happen
- anticipate will happen
- imagine happening.
Sentence in the question is the were-subjunctive and we use were subjunctive after
- if
- as if
- wish
- suppose
Examples:
- I would go if I were younger.
- If he were so smart, he would call the police
- She acts as if she were the president.
- I wish the computers were working.
