324536 Assertion :
Disruption of the natural structure of a protein is called denaturation.
Reason :
The change in colour and appearance of precipitates during cooking an egg is due to denaturation.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
