I am a doctor . . . . . . . my wife is a nurse. A. when B. while C. so D. because

when
while
so
because

The correct answer is: B. while

The sentence “I am a doctor while my wife is a nurse” means that the speaker is a doctor and his wife is a nurse. The two clauses are joined by the subordinating conjunction “while”, which indicates that the two actions happen at the same time.

The other options are incorrect because they do not convey the same meaning.

  • Option A: “when” indicates that the two actions happen at different times.
  • Option C: “so” indicates that the second action is the result of the first action.
  • Option D: “because” indicates that the second action is the reason for the first action.
