The correct option is A bio prospecting
Bioprospecting or exploring molecular, genetic and species level diversity for gaining the products of economic importance comes under narrowly utilitarian category. It also says that biodiversity should be conserved as we derive direct economic benefits from it including food, medicine, etc.
The broadly utilitarian argument talks about the conservation of biodiversity as it plays a major role in ecosystems which in turn provide us with benefits such as aesthetic value, natural resources, climate regulation, etc.
