(B)
Many animal babies grow up in the love of their parents.

The baby penguins cannot find food by themselves. So they need to get food from their parents. The mother penguin tries her best to find enough food for the babies. The father penguin keeps the baby penguins warm.
Baby swans love to be on their mother's back. Sometimes there will be three or four baby swans on the mother swan's back. The baby swan plays on the mother swan's back during the day and sleeps on the back at night.

The baby whales need to learn how to breathe (呼吸). The mother whale teaches the babies how to make the old air out from the body and get the new air. The mother also shows the babies how to swim up and catch the fish.
Every mother kangaroo has a pouch(育儿袋). It is like a big bag and car- ries the kangaroo babies in it. The pouch is warm, and the babies can eat there. The mother kangaroo keeps her babies in her pouch wherever she goes, so it's very safe for the babies.
