- 1Related to knowledge B. Ontological —
- 2Repetitious C. Epistemological —
- 3Related to diseases D. Epidemiological —
- 4Related to existence Code : A B C D
- AA-3, B-1, C-4, D-2
- BA-3, B-4, C-1, D-2
- CA-2, B-1, C-4, D-3
- DA-2, B-4, C-1, D-3
Explanation
Tautological comes from "tautology" (Greek tauto, "the same" + logos), meaning needless repetition of the same idea — A matches 2 (repetitious). Ontological derives from "ontology", the philosophical study of being and existence — B matches 4 (related to existence). Epistemological comes from "epistemology", the theory of knowledge — C matches 1 (related to knowledge). Epidemiological derives from "epidemiology", the study of the distribution of diseases — D matches 3 (related to diseases). The correct code is therefore A-2, B-4, C-1, D-3, which is option D. Note: official key disputed — the keyed C (A-2, B-1, C-4, D-3) wrongly pairs "ontological" with knowledge and "epistemological" with existence; ontology concerns existence, while epistemology concerns knowledge.
