The force with which the Earth attracts an object is called :

Result
Your answer: —  Â·  Correct: A
Explanation

The force with which the Earth attracts an object towards itself is defined as the weight of the object [3]. While this force is fundamentally the gravitational force exerted by the Earth [3], the specific term used to describe the magnitude of this pull on a particular object is its weight [3]. Weight is a vector quantity that depends on both the object's mass and the local gravitational acceleration, often expressed by the formula W = mg. In contrast, mass represents the constant amount of matter within an object and does not change regardless of location. Density refers to the mass per unit volume, and magnitude is simply a numerical value of a physical quantity. Therefore, the specific force of attraction exerted by the Earth on an object is its weight [3].
