Option B is the correct answer because “commandeering” means to officially take possession or control of (something), especially for military purposes, which matches with the given statement, hence it is correct.
Option A is incorrect because “occupation” means a job or profession and it also means the action, state, or period of occupying or being occupied by military force, but since this doesn’t indicate “forceful enlisting’ it is incorrect.
Option C is incorrect because “trespass” means to enter someone's land or property without permission, which is not necessarily for military use, hence it is incorrect.
Option D is incorrect because “encroachment “ means intrusion on a person's territory, rights which is not the same as forcefully enlisting property for military use.
