Question

Which one of the following feature is common in earthworm, butterfly, spider, and prawn?

• A. Setae
• B. Antennae
• C. Ventral nerve cord
• D. Nephridia

Answer 1

The correct option is C Ventral nerve cord

Ventral nerve cord is the common feature found in the earthworm, butterfly, spider, and prawn as they all are invertebrates.

Setae are present in Earthworm in their segments which help in the conjugation of two worms during mating. Antennae are found in butterfly which helps in locating the plant for nectar. Nephridia are the excretory organs of an earthworm. So, 'ventral nerve cord' is the right answer.
