The buoyant force on an object is created by .
A. Earth's gravity
B. a tendency to float
C. the liquid the object is in
D. air trapped inside the object

C. the liquid the object is in

Explanation:

this force is the force on an object due to its surrounding fluid

This force is always upwards that's why it is also known as upthrust

This force is due to pressure difference of the fluids on the object

So here when an object is immersed into the liquid then due to pressure difference which is higher on the bottom and lower on the top it exert force in upwards direction, this upthrust is known as buoyant force

so correct answer is

C. the liquid the object is in

i guess it’s a and b
