Consider the following programmes: I. Afforestation and development of wastelands. II. Reforestation and replantation in existing forests. III. Encouraging the wood substitutes and supplying other types of fuel. IV. Promotion of wide use of insecticides and pesticides to restrict the loss of forest area from degradation caused by pests and insects. The National Forest Policy of 1988 includes

The National Forest Policy of 1988 focuses on environmental stability, ecological balance, and the conservation of natural heritage. Statements I, II, and III are correct because the policy explicitly emphasizes the need for massive afforestation and wasteland development, the reforestation of existing forests to improve productivity, and the promotion of wood substitutes and alternative fuels to reduce the pressure on forest resources. Statement IV is incorrect because the policy focuses on natural conservation and ecological balance. The promotion of wide use of chemical insecticides and pesticides is not a part of the National Forest Policy. In fact, large scale chemical use is generally discouraged in forest conservation due to its harmful impact on biodiversity and the environment. Therefore, only statements I, II, and III are included in the policy, making D the correct option.
