Question:
Assertion [A]: Nematodes are pseudocoelomates.
Reason [R]: Perivisceral space is filled with parenchyma derived from mesoderm.
Assertion [A]: Nematodes are pseudocoelomates.
Reason [R]: Perivisceral space is filled with parenchyma derived from mesoderm.
Show Hint

- A and R are true. R is correct explanation for A.
- A and R are true. R is not correct explanation for A.
- A is true. But R is false.
- A is false. But R is true.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The assertion that nematodes are pseudocoelomates is correct. They possess a body cavity that is not entirely lined with mesoderm.
The reason is incorrect because the perivisceral space in nematodes is not filled with parenchyma but is a fluid-filled pseudocoel.
Final Answer:
A is true. But R is false.
