Let f(x)={\\begin{array}{c}(x-1) \sin \\\\\\{1\end\frac{array}{x-1} , \text{ if } x \neq 1 ; 0 , \text{ if } x=1}. Then which one of the following is true? [AIEEE 2008]

Correct Answer is : f is differentiable at x=0 but not at x=1

f is neither differentiable at x=0 nor at x=1

f is differentiable at x=0 and at x=1

f is differentiable at {\x}=0 but not at {\x}=1

f is differentiable at x=1 but not at x=0
