The correct answer is: A. Equal pay for equal work.
Mahatma Gandhi was a staunch advocate of equality and social justice. He believed that all people are equal, regardless of their caste, religion, or gender. He also believed that everyone should have the opportunity to earn a living wage and to live a dignified life.
The directive principle of equal pay for equal work is in line with Gandhi’s philosophy of equality. It ensures that all workers are paid the same wage for the same work, regardless of their gender, caste, or religion. This principle helps to promote social justice and to ensure that everyone has the opportunity to earn a living wage.
The other options are not directly related to Gandhi’s moral philosophy. Free legal aid and advice is important, but it is not a matter of equality. Ban on cow slaughter is a religious issue, and conservation of historical monuments is a cultural issue. These issues are important, but they are not directly related to Gandhi’s moral philosophy of equality.
