Explanation

On Cisco NX-OS, optional capabilities are enabled using the feature <name> syntax, so feature bash-shell is the correct command to unlock the bash shell before running commands like run bash. Option A (enable bash-shell) incorrectly borrows from IOS privilege-mode syntax, where enable means something entirely different. Option B (bash-shell enable) reverses the required word order and is not valid NX-OS syntax. Option C (service bash-shell) mimics IOS service commands (e.g., service password-encryption) but is not a valid NX-OS construct for this purpose.

Memory tip: In NX-OS, think "feature first" - any optional protocol or shell capability follows the pattern feature <name> (e.g., feature ospf, feature bgp, feature bash-shell). If you remember that NX-OS uses feature as the universal on-switch, you can eliminate all other options immediately.
