It is generally not recommended to give your password to anyone, even if they claim to be your internet service provider (ISP).
There are a number of reasons for this. First, it is important to protect your personal information and keep your passwords private. Sharing your password with anyone, even someone who claims to be your ISP, can put your personal information and online accounts at risk.
Second, there is always the possibility that someone could be pretending to be your ISP in order to obtain your password. This is known as phishing, and it is a common tactic used by hackers and other cybercriminals to trick people into giving away their personal information.
Given these considerations, it is generally best to be cautious when it comes to sharing your password. If you receive an instant message or any other communication asking for your password, you should verify the identity of the person or organization requesting it before providing it. You can do this by contacting your ISP directly using a known and trusted method of communication, such as a phone call or email from their official website.
So, the correct answer to your question would be c) I never give my password to anyone.
