Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A pure reflecting telescope does not suffer from chromatic aberration. A lens, on the other hand, bends different colors of light at different angles.
When a lens gets to be really large it gets very heavy and its own weight will distort the lens.
Both are correct but explanation is not correct.
