| a) | I and II | b) | II and III |
| c) | I, II and III | d) | I and III |
| (c)All of the above.The most important elements that lead to so much variation are temperature, water, light, soil. Physio-chemical components alone do not characterize the habitat of an organism completely. It includes biotic factors also. So for characterization of habitat both abiotic and biotic components are needed |
