The correct Answer is:
C
In an area if there are 200 Parthenium plants but only a single Banyan tree with a large canopy, stating that the population density of Banyan is low relative to that of Parthenium amounts to under estimating the enormous role of Banyan in that community. In such cases percent cover or biomass is more meaningful measure of the population size.
