\u00c0\u00ect\u00f3\u0301 \u1eb9\u0300s\u00f9n means the falsity or wrongness of an accusation, in other words, a denial that the accusation is true. A sentence that expresses this idea must state, directly, that the accused did not do what they are being blamed for.

"K\u00ec \u00ed \u1e63e \u00f2un l\u00f3 j\u00e0" translates as "it was not him or her who fought," a direct denial that the accused person is the one responsible for the fight. "\u00d3 d\u00e1j\u00fa p\u00e9 \u00f2un l\u00f3 j\u00e0" means "it is certain that it was him or her who fought," which affirms guilt rather than denying it. "K\u00f2 t\u00ed \u1eb9nik\u1eb9\u0301ni m\u1ecd\u0300 \u1ecd\u0301" means "no one knows him or her yet," which is unrelated to confirming or denying an accusation of fighting. "\u1e62\u00e9 o s\u1ecd p\u00e9 \u00f2un l\u00f3 j\u00e0?" means "did you say it was him or her who fought?", a question seeking information rather than a statement denying guilt.

Because it is the only sentence that directly rejects the claim that the accused person fought, "K\u00ec \u00ed \u1e63e \u00f2un l\u00f3 j\u00e0" is the sentence that shows denial of the accusation.

Examination tip: look for a sentence structured as a direct negation, "k\u00ec \u00ed \u1e63e...," when a question asks which statement denies or shows the falsity of an accusation.
