Which one of the following is the best representation of the titration curve which will be obtained in the titration of a weak acid (0.10 M) with a strong base of the same concentration?

the acid titration curves for acids with different strengths, pK a = 4.65, 2.90 and 1.45, at the same concentration (0.1 M), titrated with a base of pK a = 9.35 (pK b = 4.65) and at a concentration equal to 0.1 M. For the sake of comparison, the calculus using the function of hyperbolic sine given by Eq.
