I think it is B, Will is correct

This is a system of equations, in which, you have one equation to the left-hand-side and another on the right-hand-side

let's evaluate the left-hand-side then



notice, the left-hand-side turned out to be exactly the same expression as the right-hand-side, that simply means, both expressions are equal

for a system of equations, that simply means infinitely many solutions, or in short notational terms , so, "c" can be any real number except 0 or 3, because if it ever becomes 0 or 3, notice, some denominators go poof and the fraction becomes undefined.
