Convex mirrors give...

Convex mirrors are designed with a curved surface that bulges outwards. This shape allows for a wider field of vision compared to flat mirrors or concave mirrors. Option A, limited field of vision, is incorrect because convex mirrors actually provide a larger field of view. Option B, narrower field of vision, is incorrect because convex mirrors do not restrict one's vision, they in fact increase it. Option C, blurred vision at edges, is incorrect because convex mirrors are designed to reduce distortion and provide a clearer view. Therefore, D is the correct answer as it accurately describes the advantage of convex mirrors.
