Answer: B.
Explanation: The first condition of equilibrium for a particle is that the net (vector) force on it is zero, i.e. the sum of all forces = 0. Torque/rotation is not relevant for a particle (net torque = 0 is the rotational-equilibrium condition for extended bodies), and only vertical forces being zero is not sufficient.
