Which of the following statement is correct :

Acharged particle enters a region of uniform magnetic field at an angle $85^o$ to magnetic lines of force. The path of the particle is a circle.

An electron and proton are moving with the same kinetic energy along the same direction. When they pass through uniform magnetic field perpendicular to their direction of motion, they describe circular path.

There is no change in the energy of a charged particle moving in a magnetic field although magnetic force acts on it.

Both $(B)$ and $(C)$
