Back door programs refer to a type of malicious software that is designed to provide unauthorized access to a computer system. These programs are typically installed without the user's knowledge or consent, allowing the attacker to gain control over the system. The correct answer to your question is A. Back door programs allow entry at will, meaning someone who has installed such a program can access the compromised system whenever they please. This can lead to a wide range of unauthorized activities including stealing personal information, monitoring online activities, or even using the compromised system as a base for launching further attacks.

In this case, knowledge about computer security, specifically malware or malicious software, would be beneficial. Additionally, having an understanding of common cybersecurity threats and types of malware can help in distinguishing between different malicious programs.
