Question

If you enter a dark room, what happens to the size of the pupil?

• A. No change
• B. Expands
• C. Contracts
• D. None of these

Answer 1

The correct option is B

Expands

When we enter a dark room, our pupil expands because the amount of light is very less in the dark room. Hence, for us to see properly, the pupil expands to allow more light to enter our eyes.
