With reference to Neem tree, consider the following statements : 1. Neem oil can be used as a pesticide to control the proliferation of some species of insects and mites. 2. Neem seeds are used in the manufacture of biofuels and hospital detergents. 3. Neem oil has applications in pharmaceutical industry. Which of the statements given above is/are correct?

Statements 1 and 3 are correct because neem oil contains azadirachtin, a natural biopesticide that disrupts insect growth, and its antibacterial properties make it a staple in pharmaceutical applications. Option (d) is the most tempting wrong choice, but statement 2 is incorrect because neem is not a primary feedstock for biofuels (unlike Jatropha) and is used in general soaps rather than specialized industrial hospital detergents. The core concept tested is the economic and ecological utility of indigenous botanical resources.
