How many biodiversity hotspots are there in the world?

The country whose tropical rain forests possess the greatest biodiversity on earth is

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.

The following table shows the population data $(A-D)$ of ten species $a$ to $j$. Study the table and answer the following question.

Area and Number of Habitats	Species and their numbers (in thousands)
	$a, b, c, d, e, f, g, h, i, j$
$A (11)$	$2.3, 1.2, 0.52, 6.0, -, 3.1, 1.1, 9.2, -, 10.3$
$B (11)$	$10.2, -, 0.62, -, 1.5, 3.0, -, 8.2, 1.1, 11.2$
$C (13)$	$11.3, 0.9, 0.48, 2.4, 1.4, 4.2, 0.8, 8.4, 2.2, 4.1$
$D (12)$	$3.2, 10.2, 11.1, 4.8, 0.4, 3.3, 0.8, 7.3, 11.3, 2.1$

Which area among $A$ to $D$ shows the highest species diversity?
