Answer 1

The correct option is B A, B and C

Silverfish is a small, wingless insect in the order Thysanura and they respire by trachea.

A book lung is a type of respiration organ used for atmospheric gas exchange that is found in many arachnids, such as scorpions and spiders.

Sea squirt is a class in the subphylum Tunicata of sac-like marine invertebrate filter feeders and they respire by pharyngeal gills.

Dolphins breathe using a single blowhole located at the top of their heads. A muscular flap covers the blow hole, allowing a dolphin to hold its breath under water and preventing water from filling its lungs.
