In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A):If Cr is the coefficient of xr in the expansion of (1 + x)20
Reason(R) : Cr = Cn − r for any positive integer n
  • a)
    Assertion is true but Reason is false.
  • b)
    Both Assertion and Reason are true and Reason is not the correct explanation of Assertion.
  • c)
