Which type of evidence directly proves the truth?

The choice indicating direct evidence is correct because it refers to evidence that directly establishes a fact without needing any inference or presumption. For example, if a witness saw a crime take place and can testify to it, that eyewitness account is a form of direct evidence, as it provides firsthand observation of the event in question.

In contrast, circumstantial evidence relies on an inference to connect it to a conclusion of fact. Anecdotal evidence is based on personal accounts or stories rather than objective data. Testimonial evidence can also be invaluable; however, it can sometimes be subjective and influenced by personal beliefs or biases, making it less direct than the evidence that provides clear and straightforward proof of a fact.
