Badly crafted question, should say something like:

CD that has 12 selections?

And that's:

\(\text{}^{12} C _ 3\)

Answer 7

Answer 8

Answer 9

Answer 10

Answer 11

so that's 12 * 11 * 10

Answer 12

....which is \(\text{}^{12} P _ 3\), but you don't recognise that notation, so ignore that bit....
