Which option is NOT a described type of corroboration?

• A. Independent
• B. Dependent
• C. Rational
• D. Coerced

Answer: (D)

Corroboration is about evidence that supports a witness’s statement, strengthening its credibility. Independent corroboration comes from a source separate from the original testimony, providing fresh support. Dependent corroboration relies on the same information or the same source, which is less powerful because it doesn’t come from a truly new perspective. Rational corroboration ties the supporting evidence to logical or plausible reasoning that fits the claim, helping the assertion feel more believable. Coerced, on the other hand, describes how a statement was obtained—often under pressure—not a category of supporting evidence. So it isn’t considered a described type of corroboration.
