Question

Given below are two statements, one is labeled as Assertion (A) and the other one is labeled as Reason (R).
Assertion (A) : Humic acids are more resistant than fulvic acid.
Reason (R) : Humic acids have low molecular weight and simple structure than fulvic acids.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

To remember the solubility differences: Humic acid is soluble in alkali but insoluble in acid; Fulvic acid is soluble in both alkali and acid; and Humin is insoluble in both.
