In the light of the above statements, choose the correct answer from the options given below:
1. Both Statement I and Statement II are False
2. Statement I is True but Statement II is False
3. Statement I is False but Statement II is True
4. Both Statement I and Statement II are True
| Statement I: | In the nephron, the descending limb of loop of Henle is impermeable to water and permeable to electrolytes. |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R)
In light of the above statements, choose the correct answer from the options given below:
| Assertion (A): | Ascending limb of the loop of Henle is impermeable to water and allows transport of electrolytes actively or passively. |
| Reason (R): | Dilution of filtrate takes place due to efflux of electrolytes in the medullary fluid |
| 1. | (A) is True, (R) is False |
| 2. | (A) is False, (R) is True |
| 3. | Both (A) and (R) are True and (R) is the correct explanation of (A) |
| 4. | Both (A) and (R) are True but (R) is not the correct explanation of (A) |
