To answer the question regarding the two important forces for a floating body, we need to understand the principles of buoyancy and the forces acting on a floating object.

1. Buoyancy: This is the upward force exerted by a fluid that opposes the weight of an object immersed in it. According to Archimedes’ principle, the buoyant force is equal to the weight of the fluid that the body displaces.

2. Gravity: This is the force that pulls the object down toward the center of the Earth. The weight of the object (force due to gravity) plays a critical role in whether the object will float or sink.

When a body is floating, it displaces a volume of fluid equal to the weight of the body. For the body to be in equilibrium, the upward buoyant force must equal the downward gravitational force.

Given the options provided in your question, the correct answer is:

• b. buoyancy, gravity

These are the two critical forces that govern whether an object will float or sink in a fluid.
