Formal and informal fallacies – UGC NET Question

Statements A, B, D and E correctly describe formal and informal fallacies and their exam presence, whereas C is clearly wrong. A formal fallacy is a structural mistake, while informal fallacies arise from content, language or context. Modus ponens is a valid form and thus not a fallacy at all, so calling it a formal fallacy is incorrect. Recognising patterns like ad hominem and straw man is important for UGC NET reasoning, so D and E are true.

Option A:
Option A is correct because it correctly isolates C as the single false statement while preserving the accurate explanations in A, B, D and E. It reflects the distinction between valid forms and mistaken forms in logical analysis.

Option B:
Option B is wrong since it treats A as part of the wrong set, even though A properly defines what a formal fallacy is. A and C only therefore misclassifies a true definition as incorrect.

Option C:
Option C is also incorrect because it groups D with C, implying that ad hominem and straw man are wrongly described, whereas they are rightly cited as informal fallacies. C and D only thus misrepresents the list.

Option D:
Option D is wrong as it further extends the misclassification by adding B to the wrong set, despite B accurately describing informal fallacies. B, C and D only therefore fails to preserve the correct information needed for exam preparation.
