The correct option is D (i), (ii), (iii) and (iv)

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems. The main cause of the loss of biodiversity can be attributed to the influence of human beings on the over exploitation of resources, pollution, exotic species introduction, co-extinction, alien species invasion, intensive agriculture and forestry.
