The concept of Human Development was given by Mahbub-ul-Haq.

Option 1, Amartya Sen, is a renowned economist who has made significant contributions to the field of development economics. However, he did not specifically introduce the concept of Human Development.

Option 3, Sukhamoy Chakravarty, was also an economist who made important contributions to the field of development economics. However, he did not give the concept of Human Development either.

Option 4, G. S. Chaddha, is not a known figure in the field of development economics and did not contribute to the concept of Human Development.

Therefore, the correct answer is option 2, Mahbub-ul-Haq. He was a Pakistani economist who introduced the concept of Human Development in the late 1980s. He emphasized that development should not be solely measured by economic indicators such as GDP, but should also consider factors such as education, health, and quality of life, which are essential for human well-being. Haq`s concept of Human Development Index (HDI) has been widely used by policymakers and international organizations to assess and compare the development of nations.
