In column I, nature of collision between two bodies is given
\( \mathrm{P} \) while in column II some physical quantity that may remain

W conserved during the collision is given. Match the entries of column I with the entries of column II.
\begin{tabular}{|l|l|}
\hline \multicolumn{1}{|c|}{ Column I } & \multicolumn{1}{c|}{ Column II } \\
\hline i. Elastic collision & \( \begin{array}{l}\text { a. } \text { kinetic energy is } \\
\text { conserved }\end{array} \) \\
\hline ii. Inelastic collision & b. \( \begin{array}{l}\text { kinetic energy of the } \\
\text { system may increase }\end{array} \) \\
\hline \( \begin{array}{l}\text { iii. } \text { Perfectly inelastic } \\
\text { collision }\end{array} \) & \( \begin{array}{l}\text { c. } \text { kinetic energy is not } \\
\text { conserved }\end{array} \) \\
\hline \( \begin{array}{l}\text { iv. } \text { Collision between two } \\
\text { cars moving at high } \\
\text { speeds }\end{array} \) & \( \begin{array}{l}\text { d. } \text { total energy is } \\
\text { conserved }\end{array} \) \\
\hline
