• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Answer 1

The Correct Option is A

Concept: Q fever is a zoonotic disease, meaning it is transmitted from animals to humans. It is important in dairy science due to its association with livestock such as cattle, sheep, and goats.

Step 1: Understanding Assertion.

• Transmitted from animals (especially cattle, sheep, goats)
• Symptoms include:
• High fever

• Sweating Thus, Assertion is correct.

Step 2: Understanding Reason.
The causative organism:
• Coxiella burnetii (a bacterial pathogen) This organism is responsible for the disease and explains its occurrence.

Step 3: Linking both statements.
Reason correctly identifies the pathogen that causes the disease described in Assertion.

Step 4: Conclusion.
Both statements are correct and Reason explains Assertion.
