How is the rate of heart beat controlled ?

neural signal through autonommic nervous system (ANS) can a. Increase the heart beat rate b. Decrease the heart beat rate c. Increase the strength of ventricular contraction d. Decrease the speed of conduction of action potential e. Increase cardiac output f. Decrease cardiac output

Assertion : Neural signals through the sympathetic nerves can increase the rate of heart beat, the strength fo ventriculrar contraction and thereby the cardiac output. Reason : Adrenal medullary hormones can increase the cardiac output.
