User 'alice' has UID 1001 and belongs to groups 'users' and 'admin'. The gid usually matches the user's primary group, here 1001(alice). Groups listed include primary and secondary groups with their IDs.Final Answer:
uid=1001(alice) gid=1001(alice) groups=1001(alice),1002(users),1003(admin) -> Option CQuick Check:
id shows uid, gid, groups = uid=1001(alice) gid=1001(alice) groups=1001(alice),1002(users),1003(admin) [OK]
Quick Trick: id command shows user and group IDs clearly [OK]
