  • a)
    Radial symmetry is advantageous to sedentary mode of life
  • b)
    Notochord is mesodermal in origin placed between dorsal hollow nerve cord and alimentary canal in some animals
  • c)
    Pseudocoel (false coelom) derived from blastocoel of the embryo and is bounded by ectoderm and mesoderm
  • d)
    Cephalization is the concentration of sense organs, nervous tissue (brain), and food capturing organs at the anterior end

Option A is correct: Radial symmetry is advantageous for sedentary organisms as it allows them to interact with their environment from all directions.
Option B is correct: The notochord is mesodermal in origin and is positioned between the dorsal hollow nerve cord and the alimentary canal in some animals.
Option C is incorrect: A pseudocoel (false coelom) is derived from the blastocoel and is only partially lined by mesoderm. It is bounded by mesoderm on one side and ectoderm on the other, not fully mesodermal like a true coelom.
Option D is correct: Cephalization refers to the concentration of sensory organs, nervous tissue (including the brain), and food-capturing structures at the anterior end of an organism.

Incorrect Statement Explanation:

Explanation of Option C:
- Pseudocoel (false coelom) is not derived from the blastocoel of the embryo.
- It is actually derived from the blastocoel of the embryo in some animals.
- The pseudocoel is a fluid-filled body cavity that is not completely lined by mesoderm.
- It is found in organisms like roundworms (nematodes) and rotifers.
- The true coelom, on the other hand, is derived from mesoderm and is completely lined by mesoderm.
Therefore, option C is the incorrect statement as it misrepresents the origin and structure of the pseudocoel in certain organisms.
