(c) Assertion (A) is true, but Reason (R) is false.
Assertion is correct — a myopic person cannot see distant objects clearly. However, myopia is corrected by a concave (diverging) lens, not a converging lens.
The textbook clearly states that myopia is corrected using a concave lens of suitable power. The Reason incorrectly states a converging lens is used, making R false. Since A is true and R is false, option (c) is correct. Remember: myopia → concave lens; hypermetropia → convex lens.
