Given below are two statements: 
Assertion (A): Na+ reabsorption from glomerular filtrate occurs in PCT, ascending limb of loop of Henle and collecting duct 
Reason (R): Na+ is always reabsorbed by passive process in PCT, ascending limb of loop of Henle and collecting duct
 
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. Both (A) and (R) are False.

Consider the given two statements:
Assertion (A): The ascending limb of loop of Henle is also called the diluting segment of the nephron.
 
Reason (R): In the ascending portion, the loop becomes impermeable to water and the cells of the loop actively reabsorb solutes from the luminal fluid.
 
1. (A) is True but (R) is False.
2. Both (A) and (R) are True and (R) is the correct explanation of (A).
3. (A) is False but (R) is True.
4. Both (A) and (R) are True but (R) is not the correct explanation of (A).
