To correctly match the rubrics with the chapters in Kent's Repertory:
\begin{itemize}
\item Pulse (A) is a general physical symptom and is therefore found under the chapter Generalities (III).
\item Whistling (B) as a vocalization is related to the throat and breathing, and in Kent's Repertory, such symptoms are located under the chapter Larynx and Trachea (IV).
\item Mania a Potu (C) refers to delirium tremens or alcohol-induced mania, which is a mental state and is therefore found under the chapter Mind (I).
\item Contraction of muscles and tendons (D) is a physical manifestation affecting the limbs and is found under the chapter Extremities (II).
\end{itemize}
Thus, the correct matching is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
