The correct answer is **up to**.
The phrase "what have you been up to" is a casual way to ask someone what they have been doing lately. It is a common way to start a conversation with someone you haven't seen in a while.
The other options are not correct:
* **busy of** is not a grammatical phrase.
* **off to** is used to describe someone who is leaving for a particular place.
* **after** is used to describe someone who is pursuing a goal or objective.
Here is an example of how to use the phrase "what have you been up to" in a sentence:
> Hey, Jack! I haven't seen you for a long time! What have you been up to?
> I've been keeping busy with work and school, but I've also been able to do some traveling and spend time with my family. What about you?
