Assertion Heart pacemaker is a life-saving device when the normal heart rate of 72-80 drops to 30-40 due to disease or some other cause.
Reason The pacemaker electrically stimulates the contractile heart walls.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion

C

Assertion is true, but Reason is false

D

Assertion is false, but Reason in true.
