JEE MainPhysicsProperties of MatterMCQ+4 / −1
Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Clothes containing oil or grease stains cannot be cleaned by water wash. Reason (R): Because the angle of contact between the oil/grease and water is obtuse. In the light of the above statements, choose the correct answer from the option given below.
  1. A
    Both (A) and (R) are true and (R) is the correct explanation of (A)
  2. B
    Both (A) and (R) are true but (R) is not the correct explanation of (A)
  3. C
    (A) is true but (R) is false
  4. D
    (A) is false but (R) is true
