There are 7,315 different combinations, thus, the correct option is c
<h3>
How many combinations are there?</h3>
If we have a set of N elements, the number of different combinations of K elements (such that K ≤ N) of these N elements that we can make is:

In this case we have K = 4 and N = 22, replacing that, we get:

So there are 7,315 different combinations, thus, the correct option is c.
