(b) 2 and 3
(c) 1, 2 and 3
(d) 2, 3 and 4
- (a)Glomerulus
- (b)Proximal Convoluted Tubule
- (c)Loop of Henle
- (d)Distal Convoluted Tubule

2, 3 and 4
Reason — Water is mainly reabsorbed in the proximal convoluted tubule, loop of Henle, and distal convoluted tubule of the nephron to help the body save water and prevent dehydration. The glomerulus only filters blood, it doesn't reabsorb water.
