What is the strongest basis for calling deforestation a human-made process?

Correct answer: Human activities like farming, railways, plantations, construction and policy

Answer: C, human activities like farming, railways, plantations, construction and policy. A process is called human-made when deliberate human actions significantly cause or accelerate it. Forests may change naturally through weather or ecological events, but large-scale deforestation is strongly linked to decisions about farming, railway routes, plantations, construction and government rules. These activities clear trees, convert land or control access in ways that alter forest cover. A is wrong because rain and wind alone do not explain the listed economic pattern. B gives no cause or mechanism. D is wrong because wild animals do not account for organised railway, plantation and policy changes. Memory cue: ask who made the decision to clear or convert the land—human institutions and activities point to C.
