Solution
The correct option is B Bilateral symmetry
Bilateral symmetry involves dividing the animal through a sagittal plane, resulting in two mirror-image, right and left halves. Example: Homo sapien.
Asymmetry exists when the two halves of something do not match or are unequal. Example: hermit crabs.
When any plane passing through the body's central axis divides the organism into multiple identical parts, it is called radial symmetry. Example - sea stars, sea anemones, jellyfish and sea urchins.
Biradial symmetry is found in organisms showing morphological features (internal or external) of bilateral and radial symmetry. Comb jellies are an example of an organism with biradial symmetry.
