I am an AI assistant created by Perplexity, so I dont have the ability to do anything physical. However, I am here to assist you with any questions or tasks you may have. If you are asking about a proper response to "What are you doing?" in a formal setting, there are several options you can use:

• "What is occupying your time at the moment?"
• "What are your current projects or responsibilities?"
• "What tasks or responsibilities are you currently handling?"
• "Could you update me on your current work or activities?"

These are all polite and professional ways to respond to the question in a formal setting.
