To answer this question, let's understand the output of the ls -l command.

The ls -l command is used in Unix-like operating systems to list the files and directories in a directory. When you issue this command, it displays detailed information about each file or directory in a long format.

The output of the ls -l command consists of multiple columns. Each column represents different attributes of the file or directory. The columns are as follows:

1. The first column represents the file type and permissions.
2. The second column represents the number of hard links to the file or directory.
3. The third column represents the owner of the file or directory.
4. The fourth column represents the group of the file or directory.
5. The fifth column represents the file size in bytes.
6. The sixth column represents the last modified date and time of the file or directory.
7. The seventh column represents the file or directory name.

Therefore, the column that contains all the details of the permissions of a file when you issue the ls -l command is the first column.

The correct answer is option D) first.
