The correct answer is option 1. Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion. Here, theassertion says that flamingos migrate to warmer areas like Iraq and India during winter which is true. Flamingos cannot survive in the cold so they tend to moveto a warm place that’s why they migrate. India and Iraq are warm compared to western countries so flamingos migrate there. All other options are wrongbecause both assertion and reason are true and the Reason is the correct explanation of the Assertion.
