Solution(By Examveda Team)

If you 'care for someone', you provide the things they need and are responsible for their health. It is used mainly to talk about children, old people, and sick people.
For example - She had to give up her job to care for her elderly mother.
If you take 'care of' a person or animal, you provide for their needs.
