Solution

The correct option is B SA node and AVN
Sino-atrial node (SA node) is located the right upper corner of the right atrium and AVN(AV node) is located in the lower-left corner of the right atrium close to the atrioventricular septum.
The SAN can generate the maximum number of action potentials, i.e., $70 - 75 m i n^{- 1}$ , and is responsible for initiating and maintaining the rhythmic contractile activity of the heart. Therefore, it is called the pacemaker. From the SA node, the action potential is conducted from the atria to ventricles by AVN.
Hence the action potential is conducted from the atria to ventricles via SA node and AVN.
So, the correct answer is 'SA node and AVN'.
