None of the above

Detailed explanation-1: -Objects that are denser have a greater concentration of mass, thus creating a larger gravitational pull than a same-sized object with lower density-i.e., a cubic foot of solid rock will exert a larger pull on its surroundings than a cubic foot of ocean.
Detailed explanation-2: -Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass.
Detailed explanation-3: -As you get closer to the center of the Earth, there are fewer and fewer layers, and eventually, there’s nothing left at the center! The reason why gravity goes up ever so slightly within the Earth is that you get close to the much denser core material.
Detailed explanation-4: -Gravity is affected by the size of objects and the distance between objects. A measure of the amount of matter in an object is mass. An object with a greater mass falls faster than an object with a smaller mass. When the distance between two objects increases, the force of gravity decreases.
