Plagiarism detection tools – UGC NET Question

Statement C is the only wrong statement because academic honesty cannot be judged solely by a similarity score. Statements A, B and D correctly state that tools compare text with databases, highlight overlaps and that teachers must interpret the results. A zero score does not automatically prove originality, and non-zero scores may include properly cited material, so human judgement is essential. Thus, the option that chooses only C as wrong is correct.

Option A:
Option A is incorrect because it groups A and C as wrong statements. Statement A is in fact a core description of how plagiarism detection tools operate. Combining a true statement with a false one makes this option inconsistent.

Option B:
Option B is correct because it singles out C as the sole incorrect statement and accepts A, B and D as accurate. It acknowledges both the utility and the limits of automated similarity checking in maintaining academic integrity.

Option C:
Option C is incorrect because it labels B and C as wrong. While C is wrong, B is true in stating that similarity reports highlight matching text segments. Treating B as wrong misrepresents the basic output of these tools.

Option D:
Option D is incorrect because it declares A, B and C all wrong, even though A and B correctly describe the comparison and reporting functions. Only C is problematic, so this option cannot be accepted.
