Answer:
B). Deforestation.
Step-by-step explanation:
Lately, the human interactions with the water bodies in the South(includes India, Pakistan, Afghanistan, Sri Lanka, etc.) and the South-East Asia(Indonesia, Myanmar, Singapore, etc.) has given rise to various environmental concerns like excess flooding, depreciation in biodiversity, the decreased growth of coral reefs, etc. which has affected environment deeply.
As per the question, Deforestation among the given options is not associated with these human interaction with water bodies like Bay of Bengal, Indian Ocean, or Arabian sea. It is rather described as 'the process of clearing of trees from a large area to make it available for various other purposes' which is more associated with humans' deliberate cutting of trees. Thus, option B is the correct answer.
