a. Volunteer Tourism
b. Medical Tourism
c. Nature Tourism
d. Heritage Tourism

The correct answer is d. Heritage Tourism

Explanation:

Tourism is a socio-economic activity that involves the participation of cultural elements. Heritage Tourism is the type of tourism where the elements that make up the culture of a town are shown to the tourist, contributing to the rescue and conservation of both tangible and intangible heritage. In addition, it not only contributes to the recovery of these cultural assets but also plays a fundamental role in the cultural revaluation and the rescue of the identity of the peoples, since they are the main responsible for their heritage and tourism therefore contributes with the generation of optimal conditions for its conservation and preservation. The cultural and historical assets thus become ideal tourist attractions to diversify the tourist offer, expanding tourist routes and circuits.
