Explanation:
Air bladder is a gas-filled sac that helps fish to maintain buoyancy in water. However, not all fish have air bladders. The correct answer to the given question is option B, i.e., shark, as sharks do not have air bladders.
Reasons why sharks do not have an air bladder are:
1. Buoyancy control: Sharks have a special organ called the liver that is filled with oil. This oil is less dense than water and provides buoyancy to the shark, allowing it to stay afloat.
2. Depth control: Unlike bony fish that have a swim bladder to adjust their depth in water, sharks are able to control their depth by swimming. They can swim at different angles to adjust their depth in water.
3. Adaptation to environment: Sharks have evolved to live in their environment, and their body shape and buoyancy control mechanisms have adapted to suit their needs.
Therefore, it can be concluded that while some fish have air bladders to maintain buoyancy in water, sharks have evolved different mechanisms to control their buoyancy and depth in water.

Air bladder provides buoyancy to the aquatic animals thus helps them to stay at the current water depth without having to waste energy in swimming. It is found in many bony fishes but not in cartilaginous fishes. Shark being a cartilaginous fish, does not possess air bladder.
So, the correct answer is option B.
So, the correct answer is option B.
