Why did the shortage of oak forests in Britain increase demand for Indian timber?

Correct answer: Because alternative durable timber was needed for shipbuilding

The direct answer is B: an alternative durable timber was needed for shipbuilding. Oak forests in Britain had been heavily used, and the shortage of suitable oak became a serious problem when Britain needed ships for trade, naval power, and overseas expansion. Ships required strong, durable wood that could survive heavy work and long exposure to water. British authorities and companies therefore looked for timber from other regions. Indian forests, especially teak-bearing regions, became important because teak is strong and comparatively resistant to decay and water. Step by step: oak supply in Britain declined; shipbuilding still required durable wood; Britain searched for another source; Indian timber became valuable; colonial forest control and commercial cutting expanded. Option A is wrong because timber use had not stopped in India; Indian forests were being used and increasingly exploited. Option B is correct because it explains the substitution of one useful timber source by another for shipbuilding. Option C is wrong because Indian forests contained many useful tree species. Option D is wrong because Britain did not leave maritime trade; its naval and commercial activities were major reasons for the demand. The key idea is resource substitution: when one source becomes scarce, demand rises for a suitable replacement. Memory cue: British oak shortage plus ships equals greater demand for Indian durable timber.
