Which one of the following pairs is correctly matched?

The correct answer is D because Sundari trees are a characteristic species of mangrove forests, specifically found in the Sunderbans delta of West Bengal. The other options are incorrect for the following reasons: Teak is primarily found in central and southern India, particularly in states like Madhya Pradesh, and not in the high altitudes of Jammu and Kashmir. Deodar is a coniferous tree native to the Himalayan region, found in states like Himachal Pradesh and Jammu and Kashmir, rather than the tropical climate of Madhya Pradesh. Sandalwood is most prominently associated with the dry deciduous forests of Karnataka and Tamil Nadu, rather than the evergreen and moist climate of Kerala.
