Assertion : X-rays are used for studying the structure of crystals.
\( P \)
Reason : The distance between the atoms of
W. crystal is of the order of wavelengths of X-rays.
(1) A
(2) B
(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
