The correct answer is: d) All of the above.
Reservation policies in Punjab provide affirmative action for Scheduled Castes and Scheduled Tribes, Other Backward Classes, and Economically Weaker Sections.
Scheduled Castes and Scheduled Tribes are groups of people who have been historically discriminated against in India. They are given special privileges in education and employment to help them overcome this discrimination.
Other Backward Classes are groups of people who are not as well-off as the upper castes. They are given special privileges in education and employment to help them improve their social and economic status.
Economically Weaker Sections are families who do not have enough money to meet their basic needs. They are given special privileges in education and employment to help them improve their lives.
Reservation policies are designed to help these groups of people overcome the disadvantages they face and have a fair chance to succeed in life.
