There is a small hole in a spherical shell of mass \( M \) and radius \( R \). A particle of mass \( m \) is dropped from point \( A \) as shown. Match the two columns for the situation shown in figure.
\begin{tabular}{l|l}
\multicolumn{1}{c|}{ Column I } & \multicolumn{1}{c}{ Column II } \\
\hline (a) Potential energy from A to \( B \) & (p) Continuously increases \\
(b) Potential energy from \( B \) to \( C \) & (q) Continuously decreases \\
(c) Speed of particle from \( B \) to \( C \) & (r) \( \begin{array}{l}\text { First increases then } \\
\text { remains constant }\end{array} \) \\
(d) Acceleration of particle from & (s) \( \begin{array}{l}\text { None of these }\end{array} \) \\
\hline
\end{tabular}
