Which theory regarding the function of the stabilimentum relates to its strong reflection of ultraviolet (UV) light?

It functions as an insect lure attracting flies and bees

One of the leading, albeit paradoxical, explanations for the existence of the stabilimentum is its role as a visual beacon to attract small prey. Scientists have determined that the silk making up this structure strongly reflects ultraviolet (UV) light. Since many primary insect food sources, including various species of flies and bees, possess excellent vision in the UV spectrum, this reflected light functions as a highly visible target. The zigzag pattern effectively draws these insects directly toward the center of the web where the capture spiral is located, thereby enhancing the overall efficiency of the spider's food acquisition strategy.
