Answer
Option (i) is correct.

Explanation

  • Convex mirrors are indeed preferred for viewing traffic behind — the assertion is correct.
  • They give a wider field of view than plane mirrors — the reason is correct.
  • The wide view is exactly why they are preferred, so the reason explains the assertion.
Both statements are true and the wider view is the correct reason convex mirrors are preferred.
