The correct answer is: Both I and II follow.
The statement says that a large number of people visiting India from country X have been tested positive for carrying viruses of a killer disease. This means that there is a high risk of people from country X bringing the disease into India.
Course of action I is to put a complete ban on people coming to India from country X. This would help to reduce the risk of the disease spreading to India. However, it would also prevent people from India who are living in country X from returning home.
Course of action II is to set up detection centres at all airports and seaports to identify and quarantine those who are tested positive. This would help to identify and isolate people who are infected with the disease, which would help to prevent the spread of the disease.
Both course of action I and II would help to reduce the risk of the disease spreading to India. Therefore, both I and II follow.
Here is a more detailed explanation of each option:
- Option A: Only I follows
This option is incorrect because course of action II would also help to reduce the risk of the disease spreading to India.
- Option B: Only II follows
This option is incorrect because course of action I would also help to reduce the risk of the disease spreading to India.
- Option C: Either I or II follows
This option is correct because both course of action I and II would help to reduce the risk of the disease spreading to India.
- Option D: Neither I nor II follows
This option is incorrect because both course of action I and II would help to reduce the risk of the disease spreading to India.
- Option E: Both I and II follow
This option is correct because both course of action I and II would help to reduce the risk of the disease spreading to India.
