(b) (i) and (iii)
(c) (i), (iii) and (iv)
(d) (ii) and (iv)

Correct Answer: (c) (i), (iii) and (iv)

Explanation:

Tropical rainforests, located near the equator, that has a hot climate. Day and night are equal in length throughout the year. This forest gets plenty of rainfall. These favorable conditions lead to the presence of a large number of plants and animals in tropical rain forests.

The tropics or tropical regions are those regions of the Earth that lie roughly in the middle of the globe. It lies between the latitude lines of the Tropic of Cancer in the Northern Hemisphere, and the Tropic of Capricorn in the Southern Hemisphere including the Equator.

In the tropical rain forest, among plants, most of the tree leaves are large and dark green in color. This broad lamina helps the plant capture more sunlight for the photosynthetic process.

The branches of the rainforest trees grow at the top part of the trunk to capture more sunlight. The majority of the tree roots spread near the top of the soil to absorb more nutrients, but they do have deep, extended roots to anchor the tree to the ground. As a very less amount of sunlight can reach the floor of the rainforest, trees have adapted to grow at large heights.
