A charged particle passes through a region that could have electric field only or magnetic field only or both electric and magnetic fields or none of the fields. Match column-I with column-II.
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & \( \begin{array}{l}\text { Kinetic energy of particle } \\
\text { remains constant }\end{array} \) & p. & \( \begin{array}{l}\text { Under special } \\
\text { conditions, this is } \\
\text { possible when both } \\
\text { electric and magnetic } \\
\text { fields are present }\end{array} \) \\
\hline B. & \( \begin{array}{l}\text { Accleration of the particle } \\
\text { is zero }\end{array} \) & q. & \( \begin{array}{l}\text { the region has electric } \\
\text { field only }\end{array} \) \\
\hline C. & \( \begin{array}{l}\text { Kinetic energy of particle } \\
\text { changes and it also suffers } \\
\text { deflection }\end{array} \) & r. & \( \begin{array}{l}\text { the region has } \\
\text { magnetic field only }\end{array} \) \\
\hline D. & \( \begin{array}{l}\text { Kinetic energy of particle } \\
\text { changes but it suffers no } \\
\text { deflection. }\end{array} \) & s. & \( \begin{array}{l}\text { the region contains } \\
\text { no field. }\end{array} \) \\
\hline
