Which option correctly maintains the original integrity while avoiding ethnic bias in describing students?

Choosing to leave the description as is demonstrates a commitment to maintaining the original integrity of the data while avoiding ethnic bias. The term "Negro" used in option B, although historically prevalent, has fallen out of favor and is considered outdated and potentially offensive. Similarly, the term "Oriental" in options C and D is regarded as outdated and insensitive in contemporary contexts, as it reduces diverse cultures into a single term that lacks precision and respect for individual identities.

By opting to maintain the original wording, the answer reflects sensitivity to evolving language norms and acknowledges that while historical terms might have been used in research reporting, they do not align with current standards for inclusivity and respect. This choice avoids unnecessary re-labeling that could misrepresent or diminish the identities of the students being described.

The correct option thereby preserves the integrity of the research while steering clear of language that may perpetuate ethnic bias.
