Hint: Lizards belong to the reptiles class of the chordata of the animal group. Most of the lizards live on the land only a few of them are aquatic in nature and live in water among these few species some of them extinct and only iguanidae family are living now a day.

Complete step by step answer:
1 :- Marine Lagunas are the only living marine lizards present nowadays they belong to the genus Amblyrhynchus and the species cristatus.
2 :- marine iguanas are specifically present in the island of galapagos this is the only place where the marine fishes are present in living condition.
3 :- These are the only lizards in the world that are found in the ocean and sometimes they are found resting in the salty sea shore near the ocean.
4 :- these marine lizards have a specific ability to survive in the ocean full of algae and they make these algae their food and use them as a diet supply for them.
5 :- These lizards mainly live in the colonies near the sea shore and the females of the group get their food from the sea shore whereas male have a large size so they can obtain their food by diving in the ocean.

So here the option A is correct.

Note:
The number of the iguanas is decreasing gradually so the IUCN put them under the endangered species.
As they are endemic species and only found in Galapagos island, due to the presence of predators their numbers are decreasing day by day.
