Q. If $f(x) = \left\{ \begin{array}{r} x\sin\frac{1}{x}\ \ \ \ \ x \neq 0 \\ 0\ \ \ \ \ \ x = 0 \end{array} \right.\$, then $\lim_{x \rightarrow 0}{f(x)}$ is equal to

A) 1
B) 0
C) -1
D) None of these
Explanation

(b)
$\lim_{x \rightarrow 0}{f(x)} = \lim_{x \rightarrow 0}{x.\sin\frac{1}{x}}$
$= 0 \times finite\ term = 0$
