For every integer n ≥ 3, the function g(n) is defined as the product of all the odd integers from 1 to n, inclusive. What is the value of g(100) - g(99)?

0

3
99
100

g(n) = 1 * 3 * 5 .... * n
g(100) = 1 * 3 * 5 * ... * 99 (Note that 100 is not an odd integer, so we are not including 100 here)
g(99) = 1 * 3 * 5 * ... * 99
So, g(100) - g(99) = 0

The correct answer is A.
