Chloride cells are present in which part of teleost fishes?

Correct option is B

Chloride cells are specialized cells located in the  gills of teleost fishes, particularly in freshwater species.
· These cells are involved in the osmoregulatory process, helping the fish maintain ionic balance by excreting excess chloride ions.
· Chloride cells adapt to changes in salinity, which is crucial for fishes transitioning between freshwater and seawater environments.
· They play a key role in the fish’s ability to regulate internal salt concentrations and manage water balance.
