B.Modified long shoot
C.Modified dwarf shoot
D.Modified scale

Answer 1

Hint: Pine is any conifer that belongs to the genus of Pinus and family Pinaceae. They are evergreen and loafy trees which have their branches arranged in spiral fashion and have conical appearance.

Complete answer:
Pine trees contain resinous resinous trees which are 15–45 m (50–150 ft) tall.The smallest of pines are Siberian dwarf pine and Potosi pinyon, and the tallest is an 81.79 m (268.35 ft) tall ponderosa pine. Pines typically reach ages of 100–1,000 years.
Pines are monoecious in nature which means they have male and female cones on the same tree. Howvewer, few species are sub-dioecious which predominantly are single-sex. The male cones are usually small (1–5 cm). The female cones usually take 1.5–3 years to mature after pollination. When they mature they are nearly 3–60 cm long. They have numerous spirally arranged scales, with two seeds on each fertile scale; the scales at the base and tip of the cone are small and sterile, without seeds.The female cone is modified into long shoots.
Option A, C & D: The female cone is modified to form a long shoot. Therefore, this is the incorrect option.

Hence, the correct answer is option (B)

Note: The female cone of the Pinus is larger than the male cone of Pinus. Additionally, the male cone produces male gametophytes which are tiny small pollen grains.
Pine tree is a Gymnosperm family plant.
