The Correct Option is B

Step 1: Concept
Terrestrial Biomes and Transition Zones

Step 2: Meaning

Step 3: Analysis
The correct answer is B) Ecotone. An ecotone refers to the transitional area or zone between two adjacent biomes where there is a gradual change in the species composition of organisms. This term does not apply to benthos (underwater habitats), ecotype (a population within a species that has adapted to its specific environment), or pelagic zone (open ocean habitat).
