Why were teak and sal timber important for colonial rule?

Correct answer: Because they were useful in strong construction railways and ships

The direct answer is option C: teak and sal were valuable strong timbers used in construction, railways and ships. Their importance came from physical strength, durability and usefulness for large structures. Step by step: colonial authorities identified commercially valuable trees; teak and sal were cut and transported; the timber was used for buildings, railway sleepers or construction, and ships; demand encouraged further forest control and cutting. Option C is correct because it lists genuine imperial uses. Option A is wrong because teak and sal were not main food sources. Option B is wrong because their purpose was not to stop farming. Option D is wrong because they are substantial trees, not decorative grass. Remember: strong timber supports empire—buildings, railway sleepers and ships.
