Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Coronavirus (COVID-19) pandemic, a disease that occurred in 2020 spread all over the world. Reason (R): COVID-19 is an infectious disease caused by a newly discovered coronavirus. Choose the most appropriate answer.

• 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:

A reason may be true but still not explain the assertion. In COVID-19, being caused by coronavirus explains the disease, but not fully the global spread.

Answer 1

The Correct Option is B

Concept: COVID-19 was an infectious disease that became a global pandemic. In Assertion-Reason questions, both truth and explanation must be checked.

Step 1: Checking Assertion (A).
COVID-19 spread all over the world and became a pandemic. This statement is correct. \[ \text{COVID-19} \Rightarrow \text{Global pandemic} \]

Step 2: Checking Reason (R).
COVID-19 is an infectious disease caused by a newly discovered coronavirus. This statement is also correct. \[ \text{COVID-19} = \text{Infectious disease caused by coronavirus} \]

Step 3: Checking whether Reason explains Assertion.
The reason explains what COVID-19 is, but it does not completely explain why it spread all over the world. Global spread depends on transmission rate, travel, population movement, lack of immunity, and public health conditions. Therefore, both statements are correct, but Reason is not the correct explanation of Assertion.
