The option indicating the Merlin as the raptor most likely to capture prey in a ringing flight style is accurate because Merlins are known for their unique flight patterns, which include high-speed chases and agile maneuvering. A distinct characteristic of their hunting behavior is their ability to rapidly change direction while chasing prey, often in a series of circular or elliptical arcs that can be described as "ringing." This type of flight allows them to surprise and capture smaller birds mid-air, showcasing their adaptability and skill as hunters.

In contrast, other birds of prey listed, such as the Goshawk, American Kestrel, and Red-tailed Hawk, employ different strategies that may not focus on this ringing flight style. Goshawks tend to rely on powerful, direct bursts of speed and strength to capture prey, often hunting in forests. American Kestrels may hover or hunt from perches but do not typically exhibit the same flight dynamics as Merlins. Red-tailed Hawks often hunt from a height and glide with broad wings, utilizing thermal currents rather than engaging in the fast-paced aerial agility characteristic of the Merlin. Thus, the distinctive flight style of the Merlin sets it apart in this context, making it the correct choice for capturing prey in a ringing flight
