Which of the following adaptations help the aquatic organism in water?

The correct option is A

Streamlined body and webbed feet

The bodies of most aquatic animals are streamlined. A streamlined body shape is one that is narrow at both ends and broad in the middle. This shape enables the animals to swim faster (E.g. fish, penguin, and dolphin). These animals need to swim fast to catch their prey or swim away from predators.
