Which one of the following pairs of geographical areas show maximum biodiversity in our country?

Read the following statements:
$(A)$ Tropics harbour more species than temperate or polar areas.
$(B)$ Colombia located near the equator has nearly $1400$ species of birds.
$(C)$ India has less than $105$ species of birds.

Initially $A$ biodiversity hot spots were identified but subsequently nine more have been added to the list,bringing the total number of biodiversity hot spots in the world to $B$. These hot spots are the regions of accelerated habitat loss. Three of these hot spots—Western Ghats and Sri Lanka,Indo-Burma,and Himalaya—cover our country's exceptionally high biodiversity regions. Although all the biodiversity hot spots put together cover less than $C$ $\%$ of the earth's land area,the number of species they collectively harbour is extremely high,and the strict protection of these hot spots could reduce the ongoing mass extinctions by almost $D$ $\%$. $A, B, C$ and $D$ in the paragraph refer to:
