Which of the following checks should you always perform before clicking a link in an email?

The most comprehensive approach to ensuring safety when clicking links in emails involves a combination of multiple checks. Always checking the sender's email address helps verify if the email is coming from a legitimate source. Many phishing attempts use email addresses that may appear similar to trusted contacts or institutions but have subtle differences.

Looking for spelling and grammatical errors is also an important step because professional organizations typically proofread their communications carefully. Messages with poor language may indicate a fraudulent source attempting to lure individuals into providing personal information or clicking harmful links.

Hovering over the link to verify the actual URL before clicking is a critical security measure. This action allows you to view the destination of the link, giving you a clearer picture of whether the link directs you to a trustworthy website or a potentially malicious site.

By performing all these checks, you significantly reduce the risk of falling victim to phishing scams and other online threats. Therefore, recognizing the importance of all these practices leads to a safer online experience, making the option that encompasses all of these checks the correct choice.
