Answer : 4. "बांग्लादेश"
Explanation :

Bangladeshi economist Muhammad Yunus, along with the Grameen Bank he founded, received the 2006 Nobel Peace Prize for his contributions to poverty alleviation through pioneering microfinance services. By providing small loans to entrepreneurs lacking access to traditional banking, their microcredit model provided support to millions of people. Recently, Yunus faced legal troubles in Bangladesh over alleged violations of labor laws by Grameen Telecom, with critics saying it was political retaliation for his earlier opposition to government policies.
