Consider the given two statements:
Assertion: During shortening of the muscle, i.e., contraction, the ‘A’ bands get reduced, whereas the ‘I’ bands retain the length.
Reason: Contraction of a muscle fibre takes place by the sliding of the thin filaments over the thick filaments.
1. Both Assertion and Reason are false
2. Both Assertion and Reason are true and the Reason correctly explains the Assertion
3. Both Assertion and Reason are true but the Reason does not correctly explain the Assertion
4. Assertion is false but Reason is true
