The correct answer is C. Salmon.
A fish is an aquatic vertebrate animal with gills, fins, and a streamlined body that lives in water. Fish are abundant in both fresh water and salt water. They come in a wide variety of shapes and sizes, from the tiny planktonic fish to the large whale shark.
Jellyfish are not fish. They are invertebrates, which means they do not have a backbone. Jellyfish are made up of a gelatinous substance and have tentacles that they use to catch prey.
Lobsters are also invertebrates. They have a hard exoskeleton and ten legs. Lobsters are crustaceans, which means they are related to crabs and shrimp.
Whales are mammals, not fish. They have a backbone and lungs, and they breathe air. Whales are the largest animals on Earth, and they live in both fresh water and salt water.
In conclusion, the correct answer to the question “Which of the following is a fish?” is C. Salmon.
