Explanation
For $r \leq R, V=\frac{k Q}{R}$, constant everywhere inside the spherical shell.
For $r>R, V=\frac{k Q}{r}$, Decreases with $r$

Therefore for a uniformly thin spherical shell, the electric potential radially away from the centre can be represented as

Hence, option (a) is correct.
For $r>R, V=\frac{k Q}{r}$, Decreases with $r$
Therefore for a uniformly thin spherical shell, the electric potential radially away from the centre can be represented as
Hence, option (a) is correct.
