Which of the following is considered direct evidence?

Direct evidence refers to evidence that directly proves a fact without needing any inference or presumption. Testimony from a first-hand witness is classified as direct evidence because it is based on the personal knowledge of the witness regarding the events in question. This kind of testimony can assert facts that were directly observed, making it a strong form of evidence in legal and investigative contexts.

In contrast, documents that provide opinions, circumstantial facts surrounding a case, and records of previous similar incidents do not offer direct proof of the facts. Documents with opinions may help frame a perspective but do not establish facts on their own. Circumstantial facts require additional analysis to draw conclusions about what happened. Records of previous incidents can inform patterns or trends but do not provide direct proof related to the current case. Therefore, the testimony of a first-hand witness stands out as the form of evidence that directly supports a fact in question.
