(a) Protonephridia
(b) Nephridia
(c) Malpighian tubules
(d) Green glands​

Answer 1

Answer:

b :c:d

they are correct

Explanation:

the excretory system consists of a pair of Malpighian tubules that run from the midgut to the hindgut. Waste exits the body through the anus at the posterior end.

Excretory organs of Prawn are known as green glands or antennal glands. They are called green glands for their color and antennal gland for the location at the base of the second antennae.

Invertebrates such as flatworms use a nephridium as their excretory organ. At the end of each blind tubule of the nephridium is a ciliated flame cell. As the fluid passes down the tubule, solutes are reabsorbed and returned to the body fluids.

So, the correct option is '(i) Nephridia (ii)Malpighian tubules (iii) Green gland
