(c) nostrils
(d) legs

Answer 1

Option B is correct. Respiration in aquatic animals occurs by gills.

• Aquatic animals such as fishes, prawns, etc. have a special kind of respiratory organ known as gills that help them in absorbing oxygen from the water to produce energy and thereby release carbon dioxide.
• The other options are incorrect as lungs help with respiration in humans and legs are not even a part of this process while nostrils just enable the air to enter and exit the lungs.
