The correct answer is B. Sustainable development.
Sustainable development is the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It is a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.
Resettlement is the process of moving people from one place to another. It can be voluntary or involuntary, and it can be done for a variety of reasons, such as natural disasters, war, or economic development.
Rehabilitation is the process of restoring something to its former condition. It can be used to describe the restoration of a person, a place, or an object.
Mutual development is the process of two or more things developing together. It can be used to describe the development of a relationship, a business, or a country.
Sustainable development is the best option because it is the only option that takes into account the needs of future generations. The other options do not take into account the needs of future generations.
