The reason provided, "The descending limb allows active or passive transport of electrolytes," is incorrect. The descending limb of the loop of Henle is permeable to water but not to electrolytes. It allows for the passive movement of water out of the tubule, which leads to concentration of the filtrate as it descends. However, there is no active or passive transport of electrolytes in the descending limb.

Therefore, option 3 is the correct answer, indicating that the assertion is true, but the reason is false.
