Which thought helps maintain confidence after failure?

Correct answer: One failure does not define my entire ability

The governing concept is resilience: evaluating one unsuccessful attempt accurately instead of treating it as a permanent judgment of personal ability. Option A is correct because it leaves room to examine mistakes, change the method, practise, and try again. Options B, C, and D generalise one setback into hopeless conclusions or unfair comparisons, which can damage motivation and self-confidence.
