The correct answer is (C) safeda and popular.
Safeda (Eucalyptus) and popular (Populus) are commonly grown for commercial purposes in social forestry. These tree species have fast growth rates and provide valuable timber and wood products. They are often cultivated in plantations for their economic value, as they can be harvested and used for various purposes, including construction, furniture, paper, and other wood-based industries. Kikar (Acacia), jamun (Syzygium cumini), shisham (Dalbergia sissoo), and mango (Mangifera indica) are also important tree species, but they are not specifically mentioned as being grown for commercial purposes in social forestry in the provided options.
