The correct answer is C. for.
The word “for” is used to indicate the purpose or reason for something. In this case, the speaker is saying that the person is famous for their learning. This means that the person is well-known and respected for their knowledge and intelligence.
The other options are incorrect because they do not accurately convey the meaning of the sentence. The word “of” is used to indicate possession or association. The word “from” is used to indicate a source or origin. The word “with” is used to indicate a relationship or connection.
Here are some examples of how the word “for” can be used in other sentences:
- I am grateful for your help.
- The students are excited for the field trip.
- The teacher is looking for a student for the lead role in the play.
- The company is looking for a new CEO.
