Option D

Solution

Opposite charges attract each other and same charges repel each other. It can be observed that particles $1$ and $2$ both move towards the positively charged plate and repel away from the negatively charged plate.

Hence, these two particles are negatively charged. It can also be observed that particle $3$ moves towards the negatively charged plate and repels away from the positively charged plate. Hence, particle $3$ is positively charged.

The charge to mass ratio $(emf)$ is directly proportional to the displacement or amount of deflection for a given velocity. since the deflection of particle $3$ is the maximum, it has the highest charge to mass ratio.
