Let [t] denotes the (GIF) greatest integer function. Let $f\left(x\right)=x-\left[x\right],g\left(x\right)=1-x+\left[x\right]$ and $h\left(x\right)=\min \left\{f\left(x\right),g\left(x\right)\right\}x\in [-2,2]$ Then h is

continuous  $[-2,2]$but not differentiable at more than four points.

continuous $[-2,2]$ and  differentiable at  two points.

continuous and non- differentiable at four points.

None of these.
