In the light of the above statements choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): 

Assertion (A): The delay in the conduction of the impulse at the AV node is critical to the normal functioning of the human heart.
Reason (R): It ensures that the atria have ejected their blood into the ventricles before the ventricles contract.


In the light of the above statements choose the correct answer from the options given below:

1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): 
Assertion (A): If the SA node does not function, or the impulse generated in the SA node is blocked before it travels down the electrical conduction system, the heart would stop.
Reason (R): No other part of the nodal tissue of the heart is capable of generating the impulse.

In the light of the above statements choose the correct answer from the options given below:

1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
