An isolated thunderstorm is in close proximity to your aerodrome of intended landing. You should

  1. Aland giving due consideration to wind shear on final approach.
  2. Bhold over a known point clear of the thunderstorm until it is well past the aerodrome.Correct answer
  3. Cland as quickly as possible.
  4. Dadd one-half the wind gust factor to the recommended landing speed and land.

Why this is the answer

Because thunderstorms bring severe wind shear and microbursts that make a final approach hazardous (TC AIM-AIR), the safe choice is to hold clear at a known point until the cell is well past the field, then land. Rushing the approach or padding the speed still exposes you to the storm.
