Assertion (A): A lenticular cloud can remain stationary while a strong wind is blowing.
Reason (R): It marks a fixed wave crest through which the air is continuously flowing.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the apparent paradox, and the cloud is being formed at one edge and destroyed at the other continuously. The shape rather than the substance is what stays put. Pilots treat them as a reliable marker of turbulent mountain wave activity.
