The correct answer is B. To waive loans.
A rural bank is a financial institution that provides banking services to people in rural areas. These services can include accepting deposits, granting loans, and providing financial advice. Rural banks play an important role in the economy by providing access to financial services to people who would not otherwise have them. This can help to improve the lives of people in rural areas by making it easier for them to start businesses, buy homes, and save for retirement.
Waiving loans is not a function of a rural bank. This is because rural banks are businesses that need to make a profit in order to stay in business. If they were to waive loans, they would lose money and eventually go out of business. This would leave people in rural areas without access to financial services, which would hurt the economy.
The other options are all functions of a rural bank. A rural bank can accept deposits from customers, grant advances to customers, and supply inputs to farmers. These services can help to improve the lives of people in rural areas by making it easier for them to save money, borrow money, and get the supplies they need to farm.
