Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: During the process of decompression in tablet manufacturing, expansion occurs in some tablet. 
Reason R: Expansion occurs in some tablet because of Plastic deformation that has occurred during compression process. 
In light of the above statements, choose the correct answer from the options given below

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but 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 1

The Correct Option is C

To determine the correct answer to the question regarding the Assertion (A) and the Reason (R) in the context of tablet manufacturing, let's analyze each part:

1. Assertion A: During the process of decompression in tablet manufacturing, expansion occurs in some tablets.
   • This statement is true. In tablet manufacturing, decompression follows the compression phase. During decompression, elastic recovery may occur, leading to the expansion or slight increase in the size of the tablet. This is due to the release of stress that was applied during compression.
2. Reason R: Expansion occurs in some tablets because of plastic deformation that has occurred during the compression process.
   • This statement is false. Plastic deformation refers to the permanent deformation that remains even after the applied pressure is removed. It does not lead to expansion upon decompression. Instead, elastic deformation, which is reversible, is responsible for the expansion during decompression as the tablet attempts to return to its original shape.

Considering the analysis above:

• Assertion A is true because it accurately describes the phenomenon of expansion during decompression due to elastic recovery.
• Reason R is false as it incorrectly attributes this expansion to plastic deformation instead of elastic recovery.

Thus, the correct answer is: A is true but R is false.
