Answer 1

Answer:

The correct option is c) Silver oak.

Explanation:

• Grevillea robusta is an evergreen tree that grows quickly and can reach heights of 5–40 m (20–100 ft). The bark is wrinkled and dark grey. Its fern-like leaves have between 11 and 31 primary lobes and are 9 to 15 cm (4-6 in) in width and 10 to 34 cm (4 to 10 in) in length. Sometimes there are as many as four additional lobes that are each linear to narrowly triangular in shape. Just before flowering, it sheds a lot of its leaves.
• The blooms are grouped in single-sided, "toothbrush-like" clusters that are 12–15 cm (5–6 in) long and occasionally branching. Each flower's female component, the carpel, has a stalk that is 21–28 mm (0.8–1 in) long. The glabrous flowers are primarily yellowish-orange, though occasionally they can be scarlet.
• The height of Silver Oak trees can reach 25 to 35 meters. the main kind of wood used to build European timber-framed structures. Silver oak wood is still frequently used today to create a veneer, cricket bats, timber frame structures, flooring, and furniture.
