Question

Match the following:

• A. A$\text{-}$III, B$\text{-}$V, C$\text{-}$I, D$\text{-}$IV
• B. A$\text{-}$IV, B$\text{-}$V, C$\text{-}$II, D$\text{-}$I
• C. A$\text{-}$II, B$\text{-}$I, C$\text{-}$V, D$\text{-}$III
• D. A$\text{-}$III, B$\text{-}$V, C$\text{-}$I, D$\text{-}$II

Hint:

Remember excretory organs: Protonephridia → simple animals, Metanephridia → annelids, Malpighian tubules → insects, Coxal glands → crustaceans.

Answer 1

The Correct Option is A

• Rotifers $\rightarrow$ Protonephridia (A$\text{-}$III).
• Earthworms $\rightarrow$ Metanephridia (B$\text{-}$V).
• Terrestrial arthropods $\rightarrow$ Malpighian tubules (C$\text{-}$I).
• Crustaceans $\rightarrow$ Coxal glands (D$\text{-}$IV).
• Correct matching is A$\text{-$III, B$\text{-}$V, C$\text{-}$I, D$\text{-}$IV}.
