The radius of charged particle in a uniform magnetic field

$r=\frac{mv}{qB}$

therefore$r \propto \frac{m}{q}$----(i)

according to the given figure, the centre of both the curve is on the same side, hence nature of both the charge is the same.

from figure$R_M<R_N$

option$1$is incorrect as of opposite charge

option$2$is incorrect as deuteron has a greater mass hence greater radius of$M$

option$3$is incorrect as of opposite charge

option$4$is correct as of proton has a less mass hence smaller radius of$M$
