"Nah" Is correct, it is b
A solution of indicator molecules takes on the color of the most abundant form - wither the protonated or the unprotonated form. pH indicators change color at their pKa where the identity of the most abundant form changes. The pH at which the color change happens for a particular indicator depends on its Ka of Kb because this value determines the pH of the equivalence point.
The answer is b
