Answer:

B. It has mass

Step-by-step explanation:

The Newtons Universal gravitacion law is : F = G.
(m1 m2)/(d^(2) ) , where F is the force exerted , m1 and m2 are the earth's mass and the object's mass, d is the distance and G the gravitacional constant. Comparing to the options we can say that the Earth exerts a gravitational force on objects on its surface because of its mass.
