Assertion Upto elastic limit of a stress-strain curve, the steel wire tends to regain its original shape when stress is removed.
Reason Within elastic limit, the wire follows Hooke's law.

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If both Assertion and Reason are false.
