Deforestation for railways in the colonial period was linked with what kind of demand?

Correct answer: Demand for timber

The direct answer is B: demand for timber. Railways needed wooden sleepers placed beneath the rails, fuel wood for steam engines, and wood for railway structures. The reasoning is: railway lines expanded; each line required many sleepers and other wooden materials; colonial authorities obtained this timber from forests; consequently railway expansion caused extensive deforestation. Option A, demand for cloth, concerns textiles and is not the main material demand behind railway cutting. Option B is correct because timber means usable wood and was essential for railway construction and operation. Option C, demand for fish, has no necessary connection with railway tracks. Option D, demand for gold, concerns mining and money, not the wooden railway requirement. Exam cue: railway plus forests usually points to timber, sleepers and fuel wood.
