Which of the following best describes the pH values at points A, B, and C on this titration curve?

Question

Accepted Answer

A is the pH at the equivalence point;  
 
B is the pH at the half-equivalence point and equals the p K a  of the weak acid;  
 
C is the pH of the solution of the weak acid before adding NaOH
