Why did local discontent increase due to forest transformations in Java?

Correct answer: Because access to forests and resource use were restricted

Forest transformation in Java changed how local people could use land and forest resources. Colonial authorities and forest managers restricted access, controlled cutting and collection, and reorganised forests for commercial purposes, especially valuable timber. Such rules could interfere with customary rights, fuel collection, grazing, cultivation, and other activities supporting village life. When people lost access to resources on which their livelihood depended, resentment and resistance naturally increased.

Option A is correct because restricted access and resource use directly created hardship and challenged local rights. The other choices are unrelated or exaggerated: a dried sea, school holidays, or the complete disappearance of cotton does not explain the forest-based conflict. The important chain is colonial forest control, reduced livelihood opportunities, growing insecurity, and therefore local discontent.
