Statement 1: Red phosphorus is less volatile than white phosphorus Statement 2: Red phosphorus has a discrete tetrahedral structure

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