Hint: Chlorophyll is a green pigment present in the chloroplasts of algae and plants.It is one of the significant elements used in the process of photosynthesis. Photosynthesis is the process through which green plants and other organisms utilise sunlight to prepare nutrients from carbon dioxide and water.
Complete Step by Step Solution:
The colour of green plants is due to the chlorophyll pigment. Pyrrole is a five-membered heterocyclic aromatic organic compound containing a nitrogen atom.
The structure of pyrrole is as follows:
Image: Pyrrole
When four pyrrole subunits are connected through methine bridges, they form a union of heterocyclic organic compounds called porphyrins.
Methine is derived from methane and is a trivalent functional group.

Metal complexes originating from porphyrins are formed naturally.
Heme, a pigment in red blood cells and also a cofactor of the protein haemoglobin, is one type of the porphyrin complex.
Chlorophyll also originates from porphyrin.
In chlorophyll, the four pyrrole units are attached by a central metal atom which is Magnesium.
Here the central magnesium atom is enclosed by a porphyrin ring which is attached to a long carbon-hydrogen side chain called a phytol chain.
So, option B is correct.
Additional Information: The word chlorophyll originates from the Greek word khloros which means green and phyllon which means leaves.
Chlorophyll is a green pigment that works as a photoreceptor in plants.
Note: Chlorophyll has a crucial part in photosynthesis as it enables the plants to absorb energy from the light given by the sun. This energy is later used to carry on the photosynthesis process. Magnesium is an important unit of chlorophyll. Chlorophyll is categorised into five types i.e., chlorophyll a, b, c, d, and d and e.
