alleryWhich of the following is a parasitic adaptation of the leech?
AWell-developed parapodia and setae
BA four-chambered heart for circulation
CSuckers at both ends for attachment
DLungs for efficient gaseous exchange
Answer & Solution
Correct answer: C. Suckers at both ends for attachment
1. Parasitic adaptations help the leech feed on a host.
2. The anterior and posterior ends bear suckers to attach to the host.
3. So suckers at both ends are an adaptation.
4. Parapodia and setae are completely absent in the leech, so option A is the trap.
