Explanation:

- Ransomware is primarily based on the fear of losing important files.

- Correct Answer: Option 2 - Fear of losing important files.

- Ransomware is a type of malicious software that encrypts the victim's files. The attacker then demands a ransom from the victim to restore access to the data upon payment.

- Option 1: Fear of hackers

- While fear of hackers can be a concern related to cybersecurity, ransomware specifically targets the accessibility of critical data rather than the mere presence of hackers.

- Option 3: Fear of the Internet

- The Internet itself is not inherently feared in the context of ransomware; rather, it's the platform through which ransomware can be spread.

- Option 4: Fear of spyware

- Spyware relates to surveillance and data monitoring, which, although concerning, is different from the data encryption and ransom demands typical of ransomware.
