Differentiating electrons of some elements are as given, Na = `3s^1`, Al = `3p^1`, Sc = `3d^1`, Ce = `4f^2` Correct indication of their blocks :

Options

A. Na = s block, Al= p - block, Sc = d- block, Ce = f block
B. Na = p - Block, Al = s- block, Sc=f- block, Ce - d - block
C. Na = p - block, Al = d - block Sc = s - block: Ce = f- block
D. Na =f - block, Al = d - block Sc = p block, Ce = s- block
