Answer 1

-Pine tree is a conifer that belongs to the genus Pinus and is of great economical importance because the timber obtained from has great value. They are most abundant in the northern hemisphere including north America, Europe, South-East Asia, Russia and China.

Complete answer:
Pines are woody, having thick barks, branching plants possessing needle-like leaves that are shaped in the form of cones. Pines have four different kinds of leaves- seed leaves or cotyledons, juvenile leaves which are present on young plants, scale leaves and needle leaves which are found in the adult stage. Pines are famous for the production of cones. They bear both the male and female cone on the same plant, the male cone is smaller in size than the female cone. Pines are found to be suited to grow in cold environments and nutrient poor soils. Pin trees can by the virtue of dense growth form a canopy that can prevent sunlight from reaching to the floor of the forest. This prevents the growth of other plants that generally grow beneath them. In the given question the tallest among the four is Sequoia sempervirens which has a height of 111m.

Hence the correct answer option is (D) Sequoia.

Note: Pines are of importance because they produce economically significant products. The timber obtained from them are widely used in the construction furnitures, floors, roofing, window frames. Some species also produce pine nuts that are used for cooking and baking.
