हिन्दीWhich of the following statements about the reabsorption process in Henle's loop are correct? (a) The descending limb of Henle's loop is permeable to water but almost impermeable to electrolytes. (b) Urine gets concentrated in Henle's loop. (c) Reabsorption of Na$^+$ and water takes place in Henle's loop. (d) Active or passive transport of electrolytes occurs in the ascending limb of Henle's loop. Choose the correct answer from the options given below :
Correct answer · Option 4
(a), (b) and (d) only
