JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Statement 1: Colloidal solutions are stable, but colloidal particles do not settle down. Statement 2: Brownian movement counters the force of gravity acting on colloidal particles.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True
