Solution

The correct option is C
Both `A’ and `B’

Both A and B
When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it.
Upthrust = Volume of body $\times$ density of liquid $\times$ acceleration due to gravity.

Upthrust on a body depends on A. The acceleration due to gravity, the density of the liquid B. The volume of the body immersed in the liquid.

The correct option is C Both `A’ and `B’ Both A and B When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it. Upthrust = Volume of body × density of liquid × acceleration due to gravity.
