Correct answer

A. A lot of dark exhaust smoke

Comment

Dark smoke indicates increased fuel consumption. It may be causally related to a fault of the engine control. You should definitely visit a workshop. Condensation, which drips from the exhaust, or white water vapor in cold weather, however, are normal.
