Given below is the representation of the extent of global diversity of vertebrates. What groups do the portions represent?

Which sample area shows maximum diversity?

Tropical regions show the greatest level of species richness because:
$A$. Tropical latitudes have remained relatively undisturbed for millions of years,hence more time was available for species diversification.
$B$. Tropical environments are more seasonal.
$C$. More solar energy is available in the tropics.
$D$. Constant environments promote niche specialization.
$E$. Tropical environments are constant and predictable.
Choose the correct answer from the options given below.

Which of the following taxon shows maximum species diversity?
