Hello, there!
A coefficient is a number that comes before a variable and is used to multiply the variable.
A variable can never be a coefficient, so we already know that the answer cannot be B or D.
Now we are left with A and C. 4 is the exponent, not the coefficient, so the answer can't be A.
So, we are left with C. 2 multiplies x and comes before x. Therefore, our answer is C.
I hope I helped!
Let me know if you need anything else!
