Which of the following options can be a part of "Liberty indicators" while calculating HDI?

All of the above

The correct answer is option 4: All of the above

Liberty indicators basically measures the following:

a. the extent of democratic participation in social and political decision-making

b. extent of Constitutional protection given to rights of citizens’

c. ‘the extent of constitutional protection of the Independence of the Judiciary and the Rule of Law’.

However, these have not been introduced in HDI.

One such liberty indicator has actually been added in HDI as a measure of ‘the extent of democratic participation in social and political decision-making’ but it has not been given any extra weight.
