Step-by-step explanation:
"Drones put spying eyes in the sky," whether under the control of a pilot or autonomously operated, signifies the capability of unmanned aerial vehicles (UAVs) to conduct surveillance. These devices, equipped with cameras or sensors, serve various purposes, including military reconnaissance, monitoring environmental conditions, and law enforcement.
When under a pilot's control, they offer human-guided precision, while autonomous drones rely on programmed algorithms. The phrase captures the dual nature of drones—acting as tools for aerial observation and data collection, sparking discussions about privacy concerns, ethical considerations, and the evolving role of technology in surveillance within both controlled and autonomous contexts.
The correct option is d.
