Which consequence occurs when freshwater fish cannot excrete efficiently?

A)Hypertonic internal fluid causes cell lysis
B)Increased secretion of salts via gills
C)Minimised water absorption via osmosis
D)Production of concentrated, dilute urine

💡 Explanation

In freshwater fish, water influx occurs because the internal environment is hypertonic compared to the surroundings; therefore, impaired osmoregulation via insufficient excretion causes cell lysis due to excessive water accumulation rather than reduced water entry or altered salt balance.
