Assertion (A): f(x) is continuous at x = a, if $\underset{\mathrm{x}\to \mathrm{a}}{\lim }\text{⨍ (x)}$ exists and equals to f(a).
Reason (R): If f(x) is continuous at a point, then$\frac{1}{\text{⨍ (x)}}$  is also continuous at the point.

Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below:
