Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dalbergia sissoo, known commonly as Indian rosewood, is an evergreen rosewood tree, also known as sisu, sheesham, tahli, Tali and also Irugudujava. It is native to the Indian Subcontinent and Southern Iran. In Persian, it is called as Jag. Shisham is best known internationally as a premier timber species of the rosewood genus, but is also used as fuel wood and for shade and shelter. With its multiple products and tolerance of light frosts and long dry seasons, this species deserves greater consideration for tree farming, reforestation and agro forestry applications. After teak, it is the most important cultivated timber tree of Bihar, which is the largest producer of shisham timber in India.
Acacia arabica (thorn tree), Mangifera indica (mango) and Prosopis (SW) dc are not timber yielding trees. 
Therefore, the correct answer is option B.
