Assertion (A): Camouflage design must consider the detection conditions explicitly.
Reason (R): A match under visible light may fail badly under infrared imaging.

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

Answer: C

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason gives the mechanism. Vegetation reflects strongly in the near infrared, and a pigment matching it in the visible need not do so beyond 700 nm. A material indistinguishable from foliage to the eye can therefore stand out sharply under an infrared imager, which is why modern camouflage specifications extend well past the visible band.
