Acids Donate Protons to Water According to the General Equation

Acids donate protons to water according to the general equation: HA(aq) + H₂O(l) ⇌ H₃O⁺(aq) + A^-(aq)
Consider the following acids and their equilibrium constants for reaction with water at 25°C.If all the acids have the same initial concentration,which is the strongest acid (i.e.which donates the most protons to water) ?

A) HBrO,K_c = 2.0 × 10^-9
B) HNO₂,K_c = 4.5 × 10^-4
C) HF,K_c = 3.5 × 10^-4
D) HIO₃,K_c = 1.7 × 10^-1
