Which is true about expert testimony?

• A. Testimony by a layperson about a general observation.
• B. Testimony by someone with specialized training or experience allowed to offer opinions.
• C. A hearsay statement offered for truth.
• D. A testimony that is always inadmissible.

Answer: (B)

Expert testimony is opinion evidence provided by someone who has specialized training or experience and is qualified to interpret technical or complex matters for the fact-finder. This kind of witness can offer informed opinions that go beyond what a layperson could reasonably conclude from common experience, using their data, methods, and expertise to explain or clarify difficult issues. That’s why this option is the best fit: it describes a witness with specialized knowledge who is allowed to give opinions based on that expertise. By contrast, a lay witness can only describe general observations and impressions from perception, not specialized opinions. The statement about hearsay mixes up a separate rule—hearsay concerns apply regardless of expert status and don’t define what makes someone an expert. And claiming that expert testimony is always inadmissible is simply false, since it is admissible when it meets the standards for reliability, relevance, and helpfulness to the case.
