A virus is a type of malicious software (malware) that is designed to infect computer programs and files, allowing it to spread from one program to another or from one storage device to another. It usually attaches itself to a legitimate file or application and becomes active when the infected file is opened or executed. Therefore, Option B (Virus) is the correct answer.
A computer virus cannot spread on its own. It requires user action, such as opening an infected file, installing compromised software, or connecting an infected USB drive. Once activated, the virus can replicate itself and infect additional files, damage data, slow down system performance, corrupt programs, or even make the computer unusable. Some viruses are created to steal sensitive information, while others are designed simply to disrupt normal computer operations.
