The correct answer is: Only argument I is strong.
Argument I is strong because it provides a clear and convincing reason why school education should be made free in India. The argument states that making school education free is the only way to improve the level of literacy in India. This is a strong argument because it is based on the assumption that people who cannot afford to pay for school will not be able to get an education. This assumption is supported by evidence from other countries, where making school education free has led to a significant increase in the number of people who are literate.
Argument II is weak because it does not provide a clear and convincing reason why school education should not be made free in India. The argument states that making school education free would add to the already heavy burden on the exchequer. This is a weak argument because it does not take into account the potential benefits of making school education free. For example, making school education free could lead to a decrease in crime, an increase in productivity, and an improvement in the quality of life for all Indians.
In conclusion, only argument I is strong. Argument II is weak because it does not provide a clear and convincing reason why school education should not be made free in India.
