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?
