Final Answer:
Given the school setting and absence of specific details, the inference is based on the historical prevalence of Christianity in educational environments. Thus, the correct option is d) Christian.
Step-by-step explanation:
The religion of the "sportsman" who boxed Ezekiel's ears at school was Christian. This conclusion is derived from the fact that Ezekiel's ears were boxed at school, and the religious background of the sportsman is not explicitly mentioned in the question. However, given the cultural context and historical prevalence of Christianity in many school environments, it is a reasonable inference.
In the absence of specific details about the sportsman's religious affiliation, it is essential to rely on contextual clues. The mention of a school setting, where Christianity has historically been a predominant faith in many regions, points towards the likelihood that the sportsman belonged to the Christian religion. While other religions might be present in various schools globally, the question does not provide any indication to suggest a different religious background for the sportsman in this specific scenario.
In academic analysis, it is crucial to make informed and contextually reasonable assumptions when faced with incomplete information. The conclusion that the sportsman who boxed Ezekiel's ears at school was Christian aligns with the common demographic distribution of religious affiliations in educational institutions, especially in regions where Christianity has historically been a dominant faith.
Thus, the correct option is d) Christian.
