Given below are two statements labelled as Assertion (A) and Reason (R)
Assertion : Gases and liquids are called fluids.
Reason: They have the loose intermolecular forces of attraction.
Select the most appropriate answer from the options given below:

Options

A. Both A and R are true R is the correct explanation of A.
B. Both A and R are true R is not the correct explanation of A.
C. A is true but R is false
D. A is false but R is true

Answer

To analyze the given statements, we will break down the assertion and reason step by step.

### Step 1: Understand the Assertion
The assertion states that "Gases and liquids are called fluids."
- **Explanation**: Fluids are defined as substances that can flow. Both gases and liquids can change shape and flow when subjected to external forces. This characteristic is what qualifies them as fluids.

### Step 2: Understand the Reason
The reason provided is "They have loose intermolecular forces of attraction."
- **Explanation**: In gases, the intermolecular forces are very weak, allowing the molecules to move freely and occupy any available space. In liquids, the intermolecular forces are stronger than in gases but still allow for some movement, enabling liquids to flow. Hence, both states of matter have relatively loose intermolecular forces compared to solids.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now we need to determine if the reason correctly explains the assertion.
- Since both gases and liquids can flow due to their molecular movement, which is facilitated by their loose intermolecular forces, the reason indeed provides a correct explanation for the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the most appropriate answer is that both the assertion and reason are correct, and the reason is the correct explanation for the assertion.

### Final Answer
Both Assertion (A) and Reason (R) are true, and R is the correct explanation of A.
