Which of the following best defines volunteer tourism?

Volunteer tourism, often referred to as "voluntourism," is characterized by travel experiences that involve not only visiting a location but also actively contributing to the local community's development or welfare. This may include activities such as helping in schools, environmental projects, or community health initiatives. The essence of volunteer tourism is to blend the travel experience with meaningful work that benefits the host community, making it distinct from regular leisure travel.

The other options represent different concepts. While leisure travel focuses solely on enjoyment, volunteer tourism integrates purpose and contribution. A program for students studying abroad typically emphasizes educational objectives rather than volunteer work, and luxury travel ventures cater more towards indulgence and adventure rather than community service. Thus, the defining feature of volunteer tourism is the commitment to positively impact the destination, making option B the best choice.
