Which statement about the simplified binomial expansion of (a + b)n, where n is a positive integer, is true?

For a positive integer n, choosing 0 items from n items can be done in exactly 1 way, so nC0 = 1. Choosing all n items can also be done in exactly 1 way, so nCn = 1. Therefore, the true statement is that nC0 and nCn are both equal to 1.
