The correct answer is: A. about
The word “about” is the most common preposition used to express concern or worry about something. In this sentence, the speaker is telling the listener not to worry about the worries and anxieties of life.
The other options are not as appropriate in this context. The word “of” is used to express possession or association. The word “for” is used to express a reason or purpose. The word “with” is used to express a relationship or connection.
Here are some examples of how the word “about” can be used to express concern or worry:
- I’m worried about my job.
- I’m concerned about the environment.
- I’m anxious about the future.
