The correct answer is:
2 : 0
The number of radial nodes of $3 s$ and $2 p$ orbitals are 2 and 0 respectively.
Number of radial nodes $=n-l-1$
For $3 s$ orbital, number of radial nodes
$$
=3-0-1=2
$$
For $2 p$ orbital, number of radial nodes
$$
=2-1-1=0
$$
Number of radial nodes $=n-l-1$
For $3 s$ orbital, number of radial nodes
$$
=3-0-1=2
$$
For $2 p$ orbital, number of radial nodes
$$
=2-1-1=0
$$
