Cigarette smoking causes two million deaths annually in the industrial states.

  • A.Cigarette smoking has been causing two million deaths annually in the industrial states.
  • B.Two million deaths are caused annually by cigarette smoking in the industrial states.
  • C.Two million deaths are being caused by cigarette smoking annually in the industrial states.
  • D.Two million deaths have been caused annually by cigarette smoking in the industrial states

Answer: B

Correct answer: Two million deaths are caused annually by cigarette smoking in the industrial states

The active verb causes is a present simple stating a general fact, so the passive must stay present simple: are caused, plural to agree with two million deaths.

The three rejected options all shift the tense - to the present perfect continuous, the present continuous, or the present perfect - and each of those turns a standing statistic into something ongoing or recently completed.
