Let

where [x] denotes the greatest integer function, then

- a)f(x) is continuous and differentiable in for all a, provided b =2
- b)f(x) is continuous and differentiable in if f(A) = 4, b = 2
- c)f(x) is continuous and differentiable in if a = 4 and b = 0
- d)for no choice of a and b, f(x) is differentiable in

Correct answer is option 'A'. Can you explain this answer?
