The correct answer is: B. talking, doing
Explanation:
The statement “Instead of talking, prove your worth by doing something” means that instead of just talking about what you can do, you should actually do something to show your worth. This is because actions speak louder than words. If you want to be taken seriously, you need to back up your words with actions.
The other options are not as relevant to the statement. Option A, “begging, demanding”, is about asking for something in a way that is not respectful. Option C, “worrying, paying”, is about being anxious about something and then taking action to solve the problem. Option D, “writing, reading”, is about communicating your thoughts and ideas through writing and then reading what others have written. Option E, “donating, demanding”, is about giving money or other resources to a cause and then asking for something in return.
In conclusion, the correct answer is B.
