Two statements are given below:
Choose the correct answer from the options given below:
| \((\mathrm{A})\) | When the forward bias voltage across a \(\mathrm{p\text{-}n}\) junction diode increases above a certain threshold voltage, the diode current increases significantly. |
| \((\mathrm{B})\) | This current is called reverse saturation current. |
| 1. | Both Statements \((\mathrm{A})\) and \((\mathrm{B})\) are False. |
| 2. | Statement \((\mathrm{A})\) is True, but Statement \((\mathrm{B})\) is False. |
| 3. | Both Statements \((\mathrm{A})\) and \((\mathrm{B})\) are True. |
| 4. | Statement \((\mathrm{A})\) is False, but Statement \((\mathrm{B})\) is True. |

The increase in the width of the depletion region in a \(\mathrm{p\text{-}n}\) junction diode is due to:
1. reverse bias only
2. both forward bias and reverse bias
3. increase in forwarding current
4. forward bias only
