Answer:

The correct option is c.

Step-by-step explanation:

The given expression is

^{12}C_{8}

Combination formula:

^{n}C_{r}=\frac{n!}{r!(n-r)!}

Using the formula we get

^{12}C_{8}=\frac{12!}{8!(12-8)!}

^{12}C_{8}=\frac{12\times 11\times 10\times 9\times 8!}{8!(4)!}

^{12}C_{8}=\frac{12\times 11\times 10\times 9}{4\times 3\times 2\times 1}

^{12}C_{8}=495

Therefore the correct option is c.
