Which of the following statement is correct ?

Options

A. A charge particle enters a region of uniform magnetic field at an angle `85^(@)` to magnetic lines of force. The path of the particle is a circle
B. An electron and a 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
C. There is no change in the energy of a charged particle moving in a magnetic field although magnetic force acts on it
D. Two electrons enter with the same speed but in opposite direction in a uniform transverse magnetic field. Then the two describe circle of the same radius and these move in the same direction
