Match List I with List II:

	List-I		List-II
A.	Chlorophyll a	(I)	Yellow-green
B.	Chlorophyll b	(II)	Yellow
C.	Xanthophylls	(III)	Blue-green
D.	Carotenoids	(IV)	Yellow to Yellow-orange

Choose the option with all correct matches.

To match each pigment in List‑I with its characteristic colour in List‑II, consider the typical absorption and appearance of these plant pigments.

Chlorophyll a is the primary photosynthetic pigment and gives leaves their blue‑green hue. Therefore it matches (III) Blue‑green.

Chlorophyll b is an accessory pigment that absorbs light in the yellow‑green region, giving a yellow‑green appearance. Hence it matches (I) Yellow‑green.

Xanthophylls are a class of yellow carotenoid pigments. They appear yellow, so they correspond to (II) Yellow.

Carotenoids (including β‑carotene) produce colours ranging from yellow to orange, which is described as (IV) Yellow to Yellow‑orange.

Putting these matches together yields the complete correct set:

A → III,  B → I,  C → II,  D → IV.
