Question

Assertion (A): Animal skins are colloidal in nature.
Reason (R): Animal skin has positively charged particles.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. A is correct but R is incorrect
• D. A is incorrect but R is correct

Hint:

In assertion-reason questions, evaluate both the truth and the causal relationship.

Answer 1

The Correct Option is B

Animal skin is colloidal in nature due to protein content and fibrous structure.
It does have positive charge, but that is not the sole reason for colloidal nature.
Hence, both statements are correct, but (R) is not the true reason for (A).
