Final answer:
The correct answer is: B) gravity. Gravity causes the increase in pressure at the bottom of a column of water. meaning that the upward force on the bottom of an object in a fluid is greater than the downward force on the top of the object. This difference in force results in a net upward, or buoyant force on the object.
Step-by-step explanation:
The factor that causes the increase in pressure at the bottom of a column of water is gravity. Pressure increases with depth in a fluid, meaning that the upward force on the bottom of an object in a fluid is greater than the downward force on the top of the object. This difference in force results in a net upward, or buoyant force on the object.
