Concept

Plagiarism is avoided by preserving transparent attribution: borrowed words or ideas must be acknowledged, and paraphrasing does not remove the duty to cite. Similarity-detection tools are useful safeguards, but they complement rather than replace proper attribution.

Application

Apply that principle to each stated practice:

• Giving proper citation of sources preserves the link between borrowed material and its source.

• Crediting only the main author can omit co-authors or other sources whose work was used, so it is not a complete attribution practice.

• Paraphrasing correctly and giving a citation expresses the idea in new wording while still acknowledging its source.

• Replacing the original author’s name conceals authorship instead of acknowledging it.

• Using a plagiarism checker can identify suspicious textual overlap before submission and supports the final review of attribution.

Contrast

The combination sets differ according to whether they include an attribution-limiting or authorship-concealing practice:

• A, B and E includes the incomplete practice of crediting only the main author.

• B and C also includes the incomplete practice of crediting only the main author.

• C and D includes replacing the original author’s name, which conceals attribution.

Result

Thus the practices that avoid plagiarism are giving proper source citation, correctly paraphrasing with citation, and using a plagiarism checker: A, C and E only.
