We need to match the common names of trees with their scientific names.
(A) Geranium tree: This common name is often used for some species of Bauhinia, particularly those with orchid-like flowers. Bauhinia purpurea (II) (Purple Orchid Tree) or related species can be referred to by this name due to the resemblance of their flowers or foliage to geraniums in some aspects, or by regional usage.
(B) Flame of the forest: This is a very well-known common name for Butea monosperma (I), famous for its vibrant orange-red flowers that cover the tree in spring, resembling a fire.
(C) Bottle Brush: This common name accurately describes trees of the genus Callistemon, which have flower spikes resembling a bottle brush. Callistemon lanceolatus (IV) (now often Melaleuca viminalis) is a common bottlebrush species.
(D) Pride of India: This is a common name for Lagerstroemia flos-reginae (III) (syn. Lagerstroemia speciosa), known for its beautiful, showy lilac to pink flowers.
Therefore, the correct matching is:
(A) - (II)
(B) - (I)
(C) - (IV)
(D) - (III)
This corresponds to option (2).
(A)- (II), (B) -(I), (C)- (IV), (D)- (III)
