Answer is (c) (i), (iii) and (iv)

Explanation:

The tropical region has generally a hot climate because of its location around the equator. Even in the coldest month, the temperature is generally higher than about 15°C. During hot summers, the temperature may cross 40°C. Days and nights are almost equal in length throughout the year. These regions get plenty of rainfall. Because of these reasons, tropical rain forests support a large number of plants and animals.
