Consider the given two statements:
| Assertion (A): | It is important that the proximal convoluted tubule of the nephron is lined with simple cuboidal brush bordered epithelium. |
| Reason (R): | Maximum reabsorption from the ultrafiltrate takes place in this segment of the nephron. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 3. | (A) is True; (R) is False. |

Consider the given two statements:
| Assertion (A): | As the filtrate moves down the descending limb of Loop of Henle, it gets concentrated. |
| Reason (R): | The descending limb of loop of Henle is permeable to water but almost impermeable to electrolytes. |
| 1. | Both (A) and (R) are True and (R) correctly explains the (A). |
| 2. | Both (A) and (R) are True but (R) does not correctly explain the (A). |

1. Only I and II
2. Only I and III
3. Only II and III
4. I, II and III
| I: | The flow of filtrate in the two limbs of Henle’s loop is in opposite directions and thus forms a counter current. |
| II: | The flow of blood through the two limbs of vasa recta is also in a counter current pattern. |
| III: | Although there is proximity between the Henle’s loop and vasa recta, yet they do not form a counter current. |

Consider the given two statements:
