This option best describes the type of evidence used because it indicates that the author is referencing specific, empirical data derived from research that supports the claim that human actions intended to help honeybees are inadvertently harming wild bumblebees. Detailed findings from a scientific study lend credibility to the argument by grounding it in rigorous research rather than merely stating claims or descriptions without evidence.
