Where is labour demand clearly visible in colonial deforestation?

Correct answer: In plantations and construction works

The main idea is that colonial deforestation was connected not only with obtaining timber or clearing land, but also with the need for workers. Colonial governments and private companies changed forests to serve commercial and administrative purposes. Plantations required labour to clear land, plant and care for crops, harvest produce, and process it. Construction projects also needed many workers for roads, railway lines, bridges, buildings, and other infrastructure.

Therefore, option A is correct because it directly identifies plantations and construction works as places where labour demand was clearly visible. The other choices are unrelated or meaningless: forest worship is a cultural activity, trees cannot vote, and fish cannot operate railways. A complete answer should show that colonial forest use involved both land and a large human workforce, often employed under difficult conditions and for the benefit of colonial enterprises.
