These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses
Assertion The weighing machine measures the weight of a body.
Reason Weightlessness means the absence of weight.

Options

A. If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
B. If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
C. If Assertion is Trie but the Reason is False.
D. If both Assertion `&` Reason are false

Explanation

To analyze the given statements and determine the correct response, we will break down the Assertion and Reason step by step.

### Step 1: Analyze the Assertion
- **Assertion**: "The weighing machine measures the weight of a body."
- A weighing machine measures the normal force exerted by the object on it. When the object is at rest on a horizontal surface, this normal force is equal to the gravitational force acting on the object (weight). Therefore, the assertion is generally true under normal conditions (i.e., when the machine is not accelerating).

### Step 2: Analyze the Reason
- **Reason**: "Weightlessness means the absence of weight."
- Weightlessness occurs when an object is in free fall or moving in such a way that the normal force acting on it is zero. In this case, the object does not experience any contact force from a surface (like the ground or a weighing machine). However, this does not mean that the gravitational force (weight) acting on the object is absent; it simply means that the normal force is zero. Thus, the reason is misleading because it implies that weight (the gravitational force) is absent, which is not correct.

### Step 3: Conclusion
- Since the assertion is true under normal circumstances, but the reason is false because it misinterprets the concept of weightlessness, we can conclude that:
- **Correct Response**: Both the Assertion and Reason are not true in the context provided.

### Final Answer
- The correct response is **D**: Both Assertion and Reason are false.
