Solution
The correct option is D Both Assertion and Reason are incorrect
The
cardiac output of a person is calculated by multiplying the stroke volume and
the heart rate. Hence, to alter a person’s cardiac output both the stroke volume
and the heart rate can be altered. Consequently, the cardiac output of an
ordinary man is less than that of an athlete.Thus, the correct answer is 'Both Assertion and Reason are incorrect.'
