[amp_mcq option1=”in” option2=”on” option3=”of” option4=”with” correct=”option3″]
The correct answer is C. of.
The preposition “of” is used to indicate the subject of a conversation or discussion. In this case, the speaker is talking about a specific subject for two hours regularly. Therefore, the preposition “of” is the most appropriate choice.
The other options are not as accurate. The preposition “in” is used to indicate a location or position. The preposition “on” is used to indicate a surface or area. The preposition “with” is used to indicate a person or thing that is associated with or involved in something.
Here are some examples of how the preposition “of” is used to indicate the subject of a conversation or discussion:
- We talked of the weather.
- I’m thinking of buying a new car.
- What do you think of the new movie?
I hope this helps! Let me know if you have any other questions.
