Aripan is painting drawn on

The correct answer is C. The wall.

Aripan is painting drawn on the wall. This can be inferred from the fact that the question asks about a painting, and paintings are typically drawn on walls. Additionally, the answer choices are all objects that could potentially be painted on, and the wall is the only one that is specifically mentioned in the question.

The other answer choices are incorrect because they are not objects that are typically painted on. The floor is a surface that is typically walked on, the roof is a surface that is typically covered with shingles or tiles, and none of the above is a specific object.
