ANSWER:
D.
Explanation:
In this case, we have the following:
3 quarters, 2 dimes, 3 nickels, and 1 penny.
Let Q, quarters
Let D, dimes
Let N, nickels
Let P, penny
Now,
Since there is only 1 penny, it cannot go out twice.
But in the case of Q, D and N, if they can come out twice, there are more than one.
Then you could choose one of each, just like this:
QD
QN
QP
DN
DP
NP
Therfore, the option that includes all those options is the last option D.
