Question

Match the following tree species in Group-I with the colour of their flowers in Group-II.

Group-I	Group-II
P - Cassia fistula	1 - Scarlet red
Q - Jacaranda mimosifolia	2 - Orange
R - Erythrina indica	3 - White
S - Plumeria alba	4 - Violet blue
	5 - Bright yellow

• A. P - 1, Q - 4, R - 5, S - 2
• B. P - 5, Q - 2, R - 4, S - 3
• C. P - 5, Q - 4, R - 1, S - 3
• D. P - 2, Q - 3, R - 1, S - 4

Hint:

Fix each species' familiar bloom colour: Cassia fistula yellow, Jacaranda violet blue, Erythrina indica scarlet red, Plumeria alba white.

Answer 1

The Correct Option is C

This match is a straight species-to-flower-colour recall question, common in landscape and site-planning study for Indian avenue and campus trees. Taking each species in turn:

1. Cassia fistula (the golden shower tree, India's national tree and Kerala's state flower): its long hanging clusters of flowers are a vivid bright yellow.
2. Jacaranda mimosifolia: widely planted as an avenue tree for its dramatic bloom, this species flowers in a distinct violet blue shade that carpets the ground beneath it when the petals fall.
3. Erythrina indica (the Indian coral tree): its flowers are a bold scarlet red, growing in dense clusters on otherwise bare branches.
4. Plumeria alba (a common frangipani): its flowers are white with a pale yellow throat, and it is a familiar temple and garden tree.

So Cassia fistula pairs with bright yellow (5), Jacaranda mimosifolia with violet blue (4), Erythrina indica with scarlet red (1), and Plumeria alba with white (3). Orange (2) is the unused colour option.

Let's summarize:

• Yellow: Cassia fistula. Violet blue: Jacaranda. Scarlet red: Erythrina indica. White: Plumeria alba.
• These are standard, frequently tested landscape species, so fixing their flower colour firmly is worth doing once and for all.

The correct match is P - 5, Q - 4, R - 1, S - 3, which is option (C).
