C

**The correct answer**

**The correct answer is B: 12.**

Why is 12 the correct answer?

Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.

Then we are left with a simpler math problem: 3 + 9 – 3 + 3

The answer is therefore 12.
