Final answer:
Do not provide information to the unknown caller. Instead, hang up and contact your IT department directly using a known number to verify the caller's identity.
Step-by-step explanation:
If someone calls from an unknown number claiming to be from IT and requests information about your computer, it is important to exercise caution. The correct course of action would be to hang up and call the IT department using a number you know to be legitimate.
This ensures that you are indeed talking to someone authorized to receive such information and protects you from potential scams or phishing attempts.
If someone calls from an unknown number claiming to be from IT and asks for information about your computer, the best course of action is to hang up and call the IT department using a known number. This is because legitimate IT departments do not typically call users to request personal information over the phone.
By calling the IT department using a known number, you can verify the legitimacy of the call and safely provide any necessary information if required.
Therefore answer is b) Hang up and call the IT department using a known number.
