Correct Answer - C
We should conserve biodiversity for three reasons that have been included under three categories- narrowly utilitarian, broadly utilitarian and ethical. The broadly utilitarian arguments for conserving biodiversity say that biodiversity plays a major role in many ecosystem services that nature provides, e.g., replenshing `O_(2)` of atmosphere by plants, nutrient cycling, aesthetic value, etc. Bioprospecting (i.e., exploring molecular, genetic and species level diversity for products of economic importance) is included under narrowly utilitarian category, which is concerned with the countless direct economic benefits obtained from nature.
