Which of the following would qualify as evaluating equine by a purchaser or agent?

The correct option involves inspecting a horse before purchase because it directly relates to the process of evaluating equine for the purpose of making a buying decision. This step is critical in the purchasing process as it allows the potential buyer or their representative to assess the horse's physical condition, behavior, and suitability for their intended use. This evaluation often includes not just a visual inspection, but may also involve checking for soundness, temperament, and other specific traits relevant to the buyer's needs.

In contrast, assisting a friend in training their horse pertains more to support in a training capacity rather than an evaluation for purchase. Reviewing equine health reports for personal insight does not necessarily involve a hands-on evaluation, and instead focuses on understanding information for personal knowledge rather than making a purchasing decision. Giving care to horses boarding at a facility relates to daily management and care responsibilities, which, while important, do not reflect an evaluation process for making a purchasing decision.
