Which of the following best describes opinion/conclusion objections?

Opinion/conclusion objections refer to challenges against a witness's testimony when it is based on their personal beliefs rather than on factual evidence or direct observations. This is important in legal proceedings, as the admissibility of evidence often hinges on its relevance and reliability.

When a witness presents an opinion rather than factual information they directly observed, it can lead to a situation where the testimony lacks the necessary foundation to properly support a case. This objection aims to ensure that testimonies are grounded in actual experiences or verifiable facts, thereby maintaining the integrity of the judicial process.

For instance, if a lay witness attempts to describe their personal feelings about an event rather than recount specific actions or circumstances they observed, this would be deemed an opinion and could be objected to under this rule.

The other choices misrepresent the nature of opinion/conclusion objections. They either misstate the criteria for admissibility or confuse the role of expert witnesses in providing testimony within their domain of knowledge, which is typically broader than that of a layperson.
