Consider the given two statements:
| Assertion (A): | Juxtamedullary nephrons are crucial for the process of urine concentration. |
| Reason (R): | They have longer loops of Henle, which extend deep into the medulla, allowing more effective water reabsorption. |
| 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). |

Identify the incorrect statement regarding proximal convoluted tubule:
| 1. | It is lined by simple cuboidal brush bordered epithelium |
| 2. | It reabsorbs 70-80 % of electrolytes and water and nearly all nutrients |
| 3. | In juxta-medullary nephrons, it extends deep into the renal medulla |
| 4. | It secretes hydrogen ions, ammonia and reabsorbs bicarbonate ions to maintain the ionic and pH balance of the body fluids |
