Four particles `alpha`-particle, deuteron, electron and a `Cl^-` ion enter in a transverse magnetic field perpendicular to it with same kinetic energy. Their paths are as shown in figure. Now, match the following two columns.
| Column I | Column II |
| A. Deuteron | p. Path-1 |
| B. `alpha`-particle | q. Path-2 |
| C. Electron | r. Path-3 |
| D. `Cl^-` | s. Path-4 |
Options:
