Two identical balls A and B having velocities of \( 0.5\text{ m/s} \) and \( -0.3\text{ m/s} \) respectively collide elastically in one dimension. The velocities of B and A after the collision respectively will be

1. A
   \( 0.3\text{ m/s} \) and \( 0.5\text{ m/s} \)
2. B
   \( -0.5\text{ m/s} \) and \( 0.3\text{ m/s} \)
3. C
   \( 0.5\text{ m/s} \) and \( -0.3\text{ m/s} \)
4. D
   \( -0.3\text{ m/s} \) and \( 0.5\text{ m/s} \)
