Correct answer: C

Explanation

Social engineering attacks often use urgent and seemingly legitimate requests to trick individuals into providing sensitive information. To avoid becoming a victim, always verify the source of suspicious communications through trusted channels, such as directly contacting your IT department. This ensures you do not fall for phishing scams while addressing any genuine concerns.

  • A. Incorrect.

    Clicking the link and providing your credentials could expose sensitive information to attackers, making this a dangerous choice.

  • B. Incorrect.

    Replying to the email might confirm your email address as active to attackers, increasing the likelihood of future phishing attempts.

  • C. Correct.

    Contacting your IT department through an official company channel allows you to confirm whether the email is legitimate without risking sensitive information.

  • D. Incorrect.

    Ignoring the email might seem safe, but it does not address the potential risk of a legitimate issue or help identify malicious activity.
