Correct option is (a) True

To explain: Mass is only of one type. So the gravitational force is always attractive. Between two neutral objects, the gravitational force goes on adding over all pairs of particles of the two objects while the electromagnetic forces being equally attractive and repulsive, add up to zero. That is why large scale motion in the universe is controlled by the weakest gravitational force.
