a. `15`
b. `-15`
c. `0`
d. `51`

A

15

B

-15

C

0

D

51

Text Solution

Verified by Experts

The correct Answer is:
C
As we know that `.^(n)C_(0)-.^(n)C_(1)^(2) + .^(n)C_(3)^(2)+"…."+(-1)^(n).^(n)C_(n)^(2) = 0` .
(if n is odd) and in the question `n = 15` (odd). Hence, sum of given series is 0.
