Options

• AUse move to move files, cd to navigate directories, and set environment variables using addenvor envor.
• BUse rm to move files, echo to navigate directories, and store environment variables in /etc/profile to persist across user sessions.
• CUse mv to move files, ls to list directory contents, and add environment variables to .bashrc to persist across sessions.
• DUse cp to move files, cd to list directory contents, and set environment variables with export to persist across sessions.

• C

• D

Explanation

Option C is correct because it pairs each task with the right tool: mv moves (renames) files without duplicating them, ls lists directory contents, and appending export VAR=value to .bashrc ensures environment variables are re-set every time a new shell session starts - achieving true persistence per user.

Why the distractors fail:

• A - move, addenvor, and envor are not valid Bash commands; they don't exist.
• B - rm removes files, it doesn't move them; echo prints text, it doesn't navigate directories. /etc/profile is system-wide, not user-specific, making it the wrong choice for a single user's persistent variables.
• D - cp copies files (leaving the original in place), so it doesn't truly move anything; cd changes directories rather than listing their contents.

Memory tip: Think "M-L-B" - Move, List, Bashrc" - mv to Move files, ls to List contents, and .bashrc for persistent Bash variables. If a command's name doesn't match its job description in the answer (like rm for "move"), it's a trap.
