Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Bovine Ephemeral Fever is also called as three day sickness.
Reason (R): Because animal dies within three days of catching infection. In the light of the above statements, choose the most appropriate answer from the options given below:

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

Hint:

“Three-day sickness” refers to duration of symptoms, not death.

Answer 1

The Correct Option is C

Concept: Assertion-Reason questions test:
• Factual correctness of both statements
• Logical relationship between them

Step 1: Analyze Assertion (A).
Bovine Ephemeral Fever (BEF) is a viral disease affecting cattle and is commonly known as “three-day sickness.”
This name arises because:
• The symptoms (fever, lameness, stiffness) appear suddenly
• The disease duration is short, typically lasting about 2–3 days \[ \text{Hence, Assertion (A) is correct.} \]

Step 2: Analyze Reason (R).
The reason states that the animal dies within three days of infection.
This is incorrect because:
• Bovine Ephemeral Fever is generally not a fatal disease
• Mortality rate is very low
• Most animals recover quickly within a few days Thus, the term “three-day sickness” refers to duration of illness, not death. \[ \text{Hence, Reason (R) is incorrect.} \]

Step 3: Check relationship between A and R.
Since Reason (R) itself is false, it cannot explain Assertion (A).

Step 4: Final conclusion. \[ \text{Assertion is correct, Reason is incorrect} \] \[ \boxed{(3)} \]
