(C) The number of radial nodes in an orbital is given by the formula: $	ext{Radial nodes} = n - l - 1$. For a $2s$ orbital,$n = 2$ and $l = 0$. $	ext{Radial nodes} = 2 - 0 - 1 = 1$. Now,let's calculate the radial nodes for the given options: $(A)$ $3d$: $n = 3, l = 2 \implies 3 - 2 - 1 = 0$. $(B)$ $5s$: $n = 5, l = 0 \implies 5 - 0 - 1 = 4$. $(C)$ $5f$: $n = 5, l = 3 \implies 5 - 3 - 1 = 1$. $(D)$ $2p$: $n = 2, l = 1 \implies 2 - 1 - 1 = 0$. Since the $2s$ orbital has $1$ radial node and the $5f$ orbital also has $1$ radial node,the correct option is $C$.

The number of radial nodes in a $2s$ orbital is equal to that in a ........ orbital.
