Which of the following organ detects depth and pressure in fish?

Solution
The correct option is B Swim bladder
Pressure detection uses the organ of weber, a system consisting of three appendages of vertebrae transferring changes in the shape of the gas bladder to the middle ear. It can be used to regulate the buoyancy of the fish.
The swim bladder or gas bladder or fish maw or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to waste energy in swimming. Thus, the correct answer is option A.
