This sentence talks about the second conditional that is used to express imaginary and impossible situations. So, second conditional uses forms of verbs in past tense. The structure of second conditional is: “If” clause (if + subject + simple past verb) followed by Main clause ( subject + would + verb). Hence, Option A is the correct answer here. Options B, C and D cannot be used as they use forms of verbs in present and future tenses.
