The density of liquid B is more than the liquid A as more upthrust is exerted on the body in liquid B and hence it sinks less.

Observation: The body sinks to a greater extent in liquid A compared to liquid B.
Conclusion: The density of liquid B is more than that of liquid A.
Explanation:
To understand why the conclusion is B, let's analyze the factors affecting the sinking of a body in a liquid.
1. Archimedes' Principle:
According to Archimedes' principle, when a body is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the body. If the buoyant force is greater than the weight of the body, the body will float, and if it is less, the body will sink.
2. Density:
Density is defined as the mass per unit volume of a substance. It determines how much mass is packed into a given volume. The density of a liquid affects the buoyant force it exerts on a body.
3. Relationship between Sinking Depth and Density:
The extent to which a body sinks in a liquid depends on the density of the liquid and the density of the body. If the density of the liquid is greater than the density of the body, the body will sink deeper. Conversely, if the density of the liquid is less than the density of the body, the body will sink to a lesser extent or float.
4. Applying the Observation:
In the given observation, the body sinks to a lesser extent in liquid B compared to liquid A. This implies that the buoyant force exerted by liquid B is less than that exerted by liquid A. Since the density of a liquid determines the buoyant force, we can conclude that the density of liquid B is more than that of liquid A.
5. Conclusion:
Based on the above analysis, we can conclude that the density of liquid B is more than that of liquid A. Therefore, option B is the correct answer.
