Which of the following best defines patriotism?

Patriotism is best defined as devotion to one’s homeland, which captures the essence of a person's love and loyalty towards their country. This devotion often manifests in a desire to support and protect national interests, culture, and values. Such feelings can inspire individuals to participate in civic duties, such as voting, serving in the military, or engaging in community service, all rooted in a sense of pride and responsibility towards their nation.

The other options, while important concepts in their own right, do not encapsulate the essence of patriotism. For instance, an obligation towards social equity pertains more to issues of fairness and justice within society rather than an individual's feelings towards their nation. An agreement among nations suggests a diplomatic or political framework for cooperation, which does not directly address personal loyalty or devotion to one's homeland. Lastly, a belief in multinationalism focuses on the cooperation and coexistence of multiple nations, which contrasts with the inward-looking commitment that defines patriotism.
