Answer: Option A

Solution(By Examveda Team)

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.
