Answer : 2. "खेजड़ी"
Explanation :

Apart from teak, Tendu, Dhavda, Gurjan, Gondal, Siris, Haldu, Khair, Semal, Reetha, Bahera and Tamarind trees are also found here. Teak is not able to tolerate much cold and frost, hence the spread of these trees is more in the southern areas. Teak wood is very useful for agricultural tools and construction works.
