Assertion (A): Cooking time in pressure cooker is reduced.
Reason (R ): The boiling point inside the pressure cooker is raised.

Options

A. If both `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is correct, but `(R )` is correct.

Explanation

To solve the assertion and reason question, let's break it down step by step.

### Step 1: Understand the Assertion
The assertion states that "Cooking time in a pressure cooker is reduced." This is a true statement. Cooking in a pressure cooker is indeed faster compared to traditional cooking methods.

**Hint:** Think about the advantages of using a pressure cooker compared to regular cooking methods.

### Step 2: Understand the Reason
The reason given is "The boiling point inside the pressure cooker is raised." This statement is actually incorrect. In a pressure cooker, the boiling point of water is increased due to the increased pressure inside the cooker.

**Hint:** Recall how pressure affects the boiling point of liquids. Higher pressure typically raises the boiling point.

### Step 3: Analyze the Relationship Between Pressure and Boiling Point
In a pressure cooker, as the pressure increases, the boiling point of water also increases. This means that water can reach a higher temperature before it starts to boil, which allows food to cook faster.

**Hint:** Consider the relationship between pressure and temperature in terms of boiling point elevation.

### Step 4: Conclusion on Assertion and Reason
While the assertion is true (cooking time is reduced), the reason provided is misleading. The boiling point does not "raise" in the context of reducing cooking time; rather, it is the increase in pressure that allows the boiling point to be higher, leading to faster cooking.

**Hint:** Differentiate between the effects of pressure on boiling point and the implications for cooking time.

### Final Answer
- Assertion (A) is true: Cooking time in a pressure cooker is reduced.
- Reason (R) is false: The boiling point inside the pressure cooker is not raised; it is actually increased due to the pressure.

Thus, the correct conclusion is that the assertion is true, but the reason is incorrect.
