Answer 1

Hint: Chlorophyll, which belongs to the most essential class of pigments used in photosynthesis, is the mechanism by which light energy is transformed by the synthesis of organic compounds into chemical energy.

Complete answer:
- In virtually all photosynthetic organisms, such as green plants, algae and cyanobacteria, chlorophyll is present. It consumes light energy, which is then used for the conversion of carbon dioxide to carbohydrates.
- Chlorophyll appears in a variety of different kinds: chlorophylls b and a are the primary types present in green algae and higher plants; chlorophylls d and a are found in various algae, often with a; chlorophyll e is an uncommon type occurring in certain golden algae; and in some bacteria, bacterio-chlorophyll exists.

Now, let us find the solution from the options-
- The photosynthetic pigments present in the Dictyota (the member of Phaeophyceae) are chlorophyll c, a, fucoxanthin and carotenoids.
-Mannitol is present in them as the food stored.
- In the red algae members (rhodophyceae) like Porphyra, chlorophyll pigment d, a and phycoerythrin are identified.
-Floridean starch is present in them as the storing of food.
- In the Chlorophyceae members, such as Volvox, chlorophyll pigment b, a and pyrenoids with starch and proteins as preserved food are contained.
- Hibiscus is a seedling in which chlorophyll b, a, carotene and xanthophyll are contained in the pigments of chlorophyll a, b, carotene and xanthophyll.
- Carbohydrates, proteins, and fats, and are processed by Leucoplast as replacement food.

Thus, the correct answer is option (B) A-IV, B-I, C-II, D-III.

Note: The chlorophyll molecule comprises the main magnesium atom bound by a structure known as a porphyrin ring containing nitrogen; a long carbon-hydrogen side chain, defined as a phytol chain, is connected to the ring.
