Hello Student,
Please find answer to your question below

Force acting on a charged moving particle in a magnetic field is given by:
\overrightarrow{F} = q\overrightarrow{v}\times \overrightarrow{B}
F = Magnetic Force
q = charge on a particle (can be +ve & -ve)
v = velocity of a particle
B = Magnetic field strength
Since F is a cross product of both v & B.
So it is normal to both v & B.
Option c is correct.
