Assertion : Deep inside a liquid density is more than the density on surface.
Reason : Density of liquid increases with increase in depth.

Options

A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer

To solve the question regarding the assertion and reason provided, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states: "Deep inside a liquid, density is more than the density on the surface."

- **Analysis**: In a liquid, the density is affected by the pressure exerted by the liquid above it. As we go deeper into the liquid, the pressure increases due to the weight of the liquid above. This increase in pressure causes the density of the liquid at greater depths to be higher than that at the surface.

### Step 2: Understand the Reason
The reason states: "Density of liquid increases with increase in depth."

- **Analysis**: This statement is true. As depth increases, the pressure increases, which in turn affects the density of the liquid. The relationship between pressure and density is direct; thus, as we go deeper, the density indeed increases.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now, we need to determine if the reason correctly explains the assertion.

- **Evaluation**: Since the reason explains why the density increases with depth (due to increased pressure), it supports the assertion that density at greater depths is higher than at the surface.

### Step 4: Conclusion
Both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.

Thus, the correct option is:
**Option A**: Both Assertion and Reason are correct, and Reason is the correct explanation of Assertion.
