Assertion (A): In high Q circuits poles of Y(s) lie close to ω axis in complex frequency plane.

Reason (R): Q is inversely proportional to damping factor.

Both A and R are true and R is correct explanation of A
Both A and R are true and R is not the correct explanation of A
A is true but R is false

If the ratio p(s)/q(s) represents a transfer function then
the degree of p(s) may be as small as zero, independent of degree of q(s)
the degree of p(s) and q(s) must be equal
the degrees of p(s) and q(s) must not be equal
the degrees p(s) and q(s) must differ by at least two
