A student titrates a \(25.0\text{ mL}\) sample of \(0.10\text{ M CH}_3\text{COOH(aq)}\) with \(0.10\text{ M NaOH(aq)}\) at \(25\ ^\circ\text{C}\). For acetic acid, \(K_a = 1.8 \times 10^{-5}\) (\(\text{p}K_a = 4.74\)) at this temperature. The titration is paused when the \(\text{pH}\) of the mixture is measured to be \(5.74\). Which of the following correctly predicts the relative concentrations of \(\text{CH}_3\text{COOH(aq)}\) and \(\text{CH}_3\text{COO}^-\text{(aq)}\) in the solution at \(\text{pH} = 5.74\), and provides the correct justification?
