Osmoregulation
B
Excretion of nitrogenous waste
C
Respiration
D
Locomotion
Answer
Excretion of nitrogenous waste
Explanation
Solution
Enteronephric nephridia are a type of excretory organ found in earthworms and play a crucial role in eliminating nitrogenous waste products, such as ammonia and urea, from the body. These nephridia are part of the earthworm's excretory system and help maintain the osmotic balance and overall internal homeostasis of the organism.
