Answer:
Correct Answer: 2. ( a )
Solution:
- The electrons are more likely to be found in the region $a$ and $c$.
At $b$, wave function becomes zero and is called radial nodal surface or simply node.
The graph between wavefunction $(\psi )$ and distance $(r)$ from the nucleus helps in determining the shape of orbital.
