Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The configuration and orientation of fibres in a yarn decides the uniformity of twisted yarn.
Reason (R): The proper drafting in different stages of spinning changes the configuration and orientation of fibres.
In the light of the above statements, choose the most appropriate answer from the options given below:
Show Hint
- Both (A) and (R) are correct and (R) is the correct explanation of (A)
- Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- (A) is correct but (R) is not correct
- (A) is not correct but (R) is correct
The Correct Option is A
Solution and Explanation
• Assertion: configuration and orientation of fibres decide the uniformity of twisted yarn. Reason: proper drafting at the various spinning stages changes the configuration and orientation of fibres.
Step 2: Detailed Explanation:
• (A) is correct: uniform yarn requires well-oriented, straightened fibres.
• (R) is correct: drafting straightens and aligns fibres.
• (R) explains how the fibre configuration and orientation that decide yarn uniformity are achieved, so it is the correct explanation of (A).
Step 3: Final Answer:
The correct option is (A) Both (A) and (R) are correct and (R) is the correct explanation of (A).
