1 heat
2 chemical
3 electrical
4 heatchemicalelectricalmechanical
Explanation:

Assertion (A): Cardiac muscle is highly resistant to fatigue. Reason (R): Cardiac muscles are innervated by the somatic nervous system
1 Both and are correct and is the correct explanation of .
2 Both and are correct but is not the correct explanation of A.
3 A is correct but R is incorrect.
4 A is incorrect but R is correct.
Explanation:
C Assertion (A) is correct- Cardiac muscle is highly resistant to fatigue because it has a high number of mitochondriawhich produce ATP. ATP is the energy source for muscle contraction. Reason is incorrect- Cardiac muscles are innervated by the autonomic nervous systemnot the somatic nervous system. The somatic nervous system controls voluntary movementswhile the autonomic nervous system control involuntary movements.
