Effect of Sodium Acetate on Weak Acid Solution

A chemist is analyzing a solution containing a weak acid (HA) with a known dissociation constant (Ka) of 1.8 x 10^-5. The chemist makes observations on how changing the concentration of sodium acetate (a salt that can produce acetate ions, A-) in the solution affects the pH. The addition of sodium acetate is expected to increase the pH because it provides a conjugate base that can react with the weak acid's dissociated form.

Given the situation above, which of the following statements about the resulting equilibrium in the solution is correct?
