Which of the following files contains information related to password aging?

Answer & Solution
Correct Answer: Option A
In Unix-like operating systems, including Linux, the /etc/shadow file stores encrypted password and other security-related information such as password aging policies for user accounts. It is readable only by the root user and provides enhanced security compared to the older /etc/passwd file.
Therefore, Option A is the correct choice.
