• B. It may result in accidental deletion of files
• C. It can expose your computer to malware or viruses
• D. It ensures compatibility with your email client

Answer: (C)

Opening attachments in emails from unknown sources poses a significant risk because such attachments can contain malware or viruses. Malware is a type of malicious software that can harm your computer or compromise your data. When you open an attachment from an unfamiliar sender, you might inadvertently execute code that can install harmful software on your system. This can lead to a variety of consequences, including data theft, loss of data, or unauthorized access to your personal information.

Understanding the nature of email attachments is critical. Attachments can be disguised as harmless files, but they may contain scripts or executable programs designed to exploit vulnerabilities in your operating system or applications. Proper cybersecurity measures include being cautious and only opening attachments from trusted sources to mitigate these risks effectively.
