Show Answer
Answer:
Correct Answer: C
Solution:
A. Enterocoel: Deuterosomes are enterocoeloms. It is formed by fusion of mesoderm lined pouches (pouches of the archentron or primitive gut). For example, Echinodermata and Chordata.
B. Schizocoel: Protostomes are schizocoelous. It is a cavity which develops by splitting the mesodermal layer in embryo. An animal developed from schizocoel is called as schizocoelomate, Eg: Annelids and arthropods.
C. Pseudocoel: It is a false coelom which is not lined by mesoderm. It is connected to archentron. Hence, coelom produced by splitting of mesoderm is schizocoel. So, the correct answer is ‘Schizocoel’.
