Answer & Solution
Correct answer: A. Control centre, containing DNA and directing activities
The nucleus is the cell's control centre. It contains DNA (organised in chromosomes), is surrounded by a nuclear membrane, and directs all activities (protein synthesis, cell division). The 'power plant' is the mitochondria.
