Correct Answer: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

Solution : The correct option is (b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

The assertion that the liberty indicator relates to political freedom is true. The liberty indicator is often used to assess the level of political freedom and civil liberties in a country. It measures the extent to which individuals enjoy political rights, such as freedom of speech, freedom of the press, and freedom of assembly.

The reason provided, stating that India initiated economic reforms in 1991, is also true. In 1991, India implemented significant economic reforms to liberalize its economy and move towards a more market-oriented system. These reforms aimed to address economic challenges and promote economic growth.

However, the reason does not directly explain the relationship between the liberty indicator and political freedom. Economic reforms and political freedom can have some interconnectedness, as improved economic conditions may positively impact political freedoms in certain cases. However, the assertion specifically refers to the liberty indicator, which primarily focuses on political freedom and civil liberties.

Therefore, while both the assertion and reason are true, the reason provided is not the correct explanation of the assertion.
