Why is it necessary to understand the difference between causes related to tea plantations and railways?

Correct answer: Because plantations needed land while railways needed timber routes and sleepers

The direct answer is option A: plantations needed land, while railways needed timber, routes, and sleepers. Tea plantations were created by clearing forest land and preparing it for a commercial crop. Railways had a different immediate demand: wood was required for sleepers, fuel, bridges, and construction, and land had to be cleared for tracks and routes. Understanding this difference matters because it shows that deforestation had several causes, not one identical cause. Option A is correct because it distinguishes the requirements while showing their common forest impact. Option B is wrong because both activities could contribute to deforestation. Option C is wrong because tea plantations grew tea; they did not mainly manufacture railway sleepers. Option D is wrong because railways were built for transport and administration, not only to grow tea. Exam cue: plantation = land for cash crop; railway = timber and transport infrastructure.
