So first, check to make sure the equation is balanced. I just looked at it, and it is (if you can't tell, that means there're the same number of each kind of atom on both sides of the equation).
The answer lies in the coefficients.
So, you'll notice there's a 3 in front of the sodium hydroxide and no coefficient (which implies 1) in front of the iron trichloride.
It's literally that simple: 3:1.
The answer is D.

M1 = 2.35 M KF
V1 = 115 mL = 0.115 L
V2 = 0.115 L + 1.28 L = 1.395 L
M2 - ?
M1*V1 = M2*V2
2.35 *0.115 = M2 *1.395
M2 = 2.35 *0.115/1.395 = 0.194 M
