Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Intercalatd discs are the dense junctions formed in between the cardiac muscle cells, where they meet each other. Intercalated discs are the specialised regions of the cell membranes. As cardiac muscle possesses considerable rhythmicity and generates its own wave of excitation, these discs function as boosters for muscle contraction wave and allow the contraction wave to be transmitted from one cardiac muscle to another.Therefore, the correct answer is option A.
