(A) Babool
(B) Laurel
(C) Sabai
(D) None of these

Answer 1

Hint: Any kind of vegetation in tropical latitudes can be called tropical vegetation. Tropical rainforests, tropical seasonal forest, tropical dry broadleaf forest, tropical grasslands, savannas, and shrublands are the major types of habitat for tropical vegetation.

Complete answer: Option (A): The babool tree belongs to tropical Africa and across Asia and it produces an inferior type of gum arabic as well as tannin which is largely used in India. Hence babool belongs to tropical vegetation.
Option (B): Laurel is an evergreen tree and it constitutes a type of subtropical forest which is found in areas with high humidity and relatively mild temperatures like subtropical eastern Asia. Thus it belongs to tropical vegetation.
Option (C): Sabai grass is grown in Asian countries having tropical vegetation and in India, it is commonly found in riverbeds and valleys of Similipal foothills of Eastern India and Shivalik foothills of Northern India.
Option (D) is correct since Babool, Laurel and Sabai, none of these are nontropical and all three belong to tropical vegetations.

Thus, The correct answer is Option D.

Note: The tropical areas of the world comprise the regions from the Tropic of Cancer in the Northern Hemisphere to the Tropic of Capricorn in the Southern Hemisphere. Divided by the equator, these regions consist of a large diversity of plant and animal species. Nearly fifty percent of known plant species are believed to originate in the regions of tropics.
