Consider the following pairs:
$$\begin{array}{ll}\text{District}& \text{Trees found in natural habitat}\\ \text{(I) Bankura}& \text{Sal}\\ \text{(II) South 24 Parganas}& \text{Sundari}\\ \text{(III) Coochbehar}& \text{Pine}\\ \text{(IV) Purba Medinipur}& \text{Baobab}\end{array}$$

How many of the pairs given above is/are correctly matched?

Let's analyze the pairs:
* (I) Bankura – Sal: Correct. Bankura lies in the Rarh region, dominated by dry deciduous forests where Sal trees are abundant.
* (II) South 24 Parganas – Sundari: Correct. Sundari trees are characteristic mangrove species found in the Sundarbans of South 24 Parganas.
* (III) Coochbehar – Pine: Incorrect. Pine trees are sub-alpine/alpine vegetation found in higher altitudes like Darjeeling, not in the plains of Cooch Behar.
* (IV) Purba Medinipur – Baobab: Incorrect. Baobab is native to Africa and not a common tree in the natural habitat of Purba Medinipur.
Thus, only two pairs are correctly matched.
