Answer:
B). By making a rule that only Country X’s authors and scholars can be taught in schools.
Step-by-step explanation:
Imperialism is described as the policy of forcefully extending a nation's authority through territorial gain or by political and economic dominance.
In the given situation, the most probable way through which country X will enforce its authority over the country Y 'by making a rule that only Country X’s authors and scholars can be taught in schools' as it will help them in propagating their ideologies and maintain their dominance/superiority over country Y. Education provides knowledge through which people become aware of their rights and it also offers the mental as physical strength to stand for their rights but without education country X will become successful in establishing their superiority over the latter. Thus, option B is the correct answer.
