# Choose the correct answer.Let f(x) = |sin x|. Then,A. f(x) is everywhere differentiable.B. f(x) is everywhere continuous but not differentiable at x = nπ, nϵZC. f(x) is everywhere continuous but not differentiable at x = (2n +1) π/2, nϵZ.D. none of these

Given that f(x) = |sin x|

From the graph it is evident that it is continuous everywhere but not differentiable at x = nπ, nϵZ
