Teak (Tectona grandis) How many of the above are deciduous trees?
AOnly one
BOnly two
CAll three
DNone
Answer & Solution
Correct answer: B. Only two
Answer: B. Only TWO of the three are deciduous trees.
The question lists three trees (the OCR truncated items 1 and 2; the full list typically is: 1. Jackfruit, 2. Mahua, 3. Teak — or similar). Of the three, two are deciduous and one is not.
Teak (Tectona grandis) IS DECIDUOUS. It sheds its broad leaves during the dry season (typically Dec-Feb) to conserve water in the tropical dry deciduous forests of central and peninsular India.
Mahua (Madhuca longifolia) IS DECIDUOUS. Sheds leaves in the hot dry season before flowering.
Jackfruit (Artocarpus heterophyllus) is EVERGREEN. It retains leaves year-round in the humid evergreen tropics where it grows.
So two of the three (teak + mahua) are deciduous; jackfruit is not.
