Answer 2

The correct option for the animal which has no segmentation is A) Hydra.

• Segmentation is a unique feature found in Annelida, Arthropoda and chordates.
• Hydra is Coelenterata so, they don't have segmentation.
• Annelida and Arthropoda organisms are non-chordates.
• The earthworm is Annelida and it increases soil fertility so, they are known to be farmers' friends.
• Arthropoda includes insects, flies, millipedes, centipedes and crustaceans.
• Cockroach and Centipedes are Arthropoda and they have jointed appendages and segmentation over their body.
