AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Although infinite rays originate from each point on an object, it is more convenient to use only two rays for clarity of the ray diagram. The two rays are chosen such that their directions after reflection from the mirror are easily known. The intersection of these two reflected rays gives the position of the image.

Examiners look for two key ideas: (1) convenience/clarity as the reason for using two rays, and (2) the principle that the intersection of two reflected rays is sufficient to locate the image point. Avoid listing the specific rays unless asked — the question is about why two rays are enough, not which rays to use.
