Option 1 : Both (A) and (R) are true and (R) is the correct explanation of (A).

Concept:

  • A loop is a closed path in a circuit where two nodes are not traversed twice except the initial point, which is also the final one.
  • But in a loop, other paths can be included inside.
  • A mesh is a closed path in a circuit with no other closed paths inside it.
  • In other words, a loop with no other loops inside it.

This is explained with the help of the following diagrams:

We, therefore, conclude that Both (A) and (R) are true and (R) is the correct explanation of (A).
