Consider the following statements and select the correct answer:
(1) If the body of most cnidarians are cut into two halves through central axis then the body would be divided into mirror images.
(2) Most of the cnidarians are triploblastic.
(3) Choanocytes are found in the gastrodermis of cnidarians.
Choose the correct answer from the codes given below:

Correct option is D

Correct Answer: (d)
Explanation:
Cnidarians (jellyfish, hydra, etc.) typically show radial symmetry, so cutting through the central axis yields mirror-image halves — statement (1) is true. They are diploblastic (two germ layers), not triploblastic, so (2) is false. Choanocytes are characteristic cells of Porifera (sponges), not cnidarians, so (3) is false.
Information Booster:
Cnidarians have two germ layers: ectoderm and endoderm (gastrodermis).
They possess a gastrovascular cavity for digestion.
Radial symmetry suits their sessile or planktonic lifestyle.
Key cell types in Porifera (choanocytes) are absent in cnidarians.
Cnidocytes (stinging cells) are diagnostic for Cnidaria.
Additional Information (Incorrect Options):
(a) Incorrect because (3) is false — choanocytes are sponge cells.
(b)/(c) Incorrect because (2) is false — cnidarians are not triploblastic.
