Answer:
The wrong command is NO CAES.
Explanation:
That command is wrong because it is not a command, as it is more like a warning or fact. It is not being properly conjugated; to be written in a correct form it should be written as: NO CAIGAS.
NO CAES is written in the simple present form, the main verb CAER is only conjugated with the second-person singular TÚ.
