Final answer:
Martin's behavior, in insisting on government responsibility for park beautification, is an example of conflict. Had he conformed to the villagers' wishes, it would have been an example of cooperation.
Step-by-step explanation:
Martin's insistence that it is the responsibility of local government to beautify the park, while the villagers want to do it themselves, is an example of conflict (A). Conflict arises when there are disagreements or different interests between parties. In this case, Martin is expressing a view that conflicts with the desire of the villagers, who prefer to take a more hands-on approach.
If Martin had conformed to the wishes of the villagers, his behavior would have exhibited cooperation (C). Cooperation occurs when individuals or groups work together towards a common goal or interest. By aligning with the villagers' wishes, Martin would be cooperating with them in their effort to beautify the park.
