Which of the following statements are correct regarding orbits and orbitals?
| (a) | An orbit is a circular path where electrons revolve. | 
| (b) | An orbital is a 3D space with maximum electron probability (up to 90%). | 
| (c) | The maximum electrons in an orbit are 2n2. | 
| (d) | Orbitals are always circular in shape. | 
| (e) | Orbitals follow the wave nature of electrons and the uncertainty principle. | 
Options:
| 1. | a, b, and c | 2. | b, c, and e | 
| 3. | a, b,c and e | 4. | a, c, and d | 
| 1. | \(\mathrm{R}\) | 2. | \(\dfrac{1}{R}\) | 
| 3. | \(\dfrac{1}{\sqrt{R}}\) | 4. | \(\sqrt{R}\) | 
| Assertion (A): | Angular momentum of the electron in the orbit that has four subshells is \(2h\over\pi\). | 
| Reason (R): | Angular momentum of the electron is quantized. | 
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). | 
| 3. | (A) is True but (R) is False. | 
| 4. | (A) is False but (R) is True. |
