Let f:(0,\infty)\toR be a differentiable function such that f'(x)=2-{f(x)}/x for all x ∊(0,\infty) and f(1)\neq1.Then [JEE Adv 2016 P1]

Correct Answer is : limx→0+f′(1x)=1

\text{lim}_{x\to0^{+}}f'(1/x)=1

\text{lim}_{x\to0^{+}}xf(1/x)=2

\text{lim}_{x\to0^{+}}x^2f'(x)=0

|f(x)|\leq2 for all x ∊ (0,2)
