The following error is encountered when running a script: Which of the following is the cause of this error?

If script.sh were missing from PATH, the shell would return 'command not found', which only applies when invoking a command without a relative or absolute path prefix.

An incorrect shebang line produces a 'bad interpreter' error, which only occurs after the shell has already located and opened the file.

A missing executable bit causes a 'Permission denied' error, which requires the file to exist and be found before the permission check runs.

When a script cannot be found at the given path, the shell returns a 'No such file or directory' error immediately upon invocation. This is distinct from permission or interpreter errors because the file is entirely absent from the filesystem, making all other execution steps unreachable.

An absent bash binary would generate a 'bad interpreter: No such file or directory' referencing the interpreter path, not the script file itself.
