Which is the most suitable example of land use change in colonial deforestation?

Correct answer: Forest land changing into fields and plantations

The direct answer is A: forest land changing into fields and plantations. Land-use change means that the same land is given a new human use. Under colonial rule, forests were cleared for cultivation, commercial plantations, railways and other economic purposes. Step by step: first, trees were cut; next, the forest area was opened; then it was used for crops or plantations that produced revenue and raw materials. Option A is correct because it gives a real change from natural forest to productive agricultural or plantation land. Option B is wrong because fields changing into natural forests is the reverse process and was not the usual meaning of colonial deforestation. Option C is wrong because a railway cannot change into a river; these are unrelated things. Option D is wrong because a market is a place or institution, while grazing land is a land-use category, and this is not the main example of colonial forest clearance. Remember: deforestation usually means forest to farm, plantation, mine, road or railway.
