Assertion : At same level of same liquid pressure is always same.
Reason : When any fluid travels from a region of higher pressure to lower pressure (At same levels) it gains same speed.

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, we will analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "At the same level of the same liquid, pressure is always the same."

- **Explanation**: According to hydrostatic pressure principles, the pressure at a certain depth in a fluid is given by the formula:
\[ P = h \cdot \rho \cdot g \]
where \( P \) is the pressure, \( h \) is the height of the liquid column above the point, \( \rho \) is the density of the liquid, and \( g \) is the acceleration due to gravity. Since \( h \), \( \rho \), and \( g \) are constant at the same level in the same liquid, the pressure will also be constant.

### Step 2: Understand the Reason
The reason states that "When any fluid travels from a region of higher pressure to lower pressure (At the same levels) it gains the same speed."

- **Explanation**: This statement is related to the principle of fluid dynamics, particularly Bernoulli's principle, which states that as the speed of a fluid increases, the pressure within the fluid decreases. However, the reason provided does not directly explain why pressure is the same at the same level in the same liquid. It discusses fluid movement and speed but does not clarify the assertion about pressure at a constant level.

### Step 3: Conclusion
- **Assertion**: True. The pressure at the same level in the same liquid is constant.
- **Reason**: True, but it does not correctly explain the assertion.

### Final Answer
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion.
