Question

by alice cary
whats better than having your own robot? having your
own robot that can fly!
maybe youve seen one of these gizmos whizzing through
the air like a flying saucer. big or small, unmanned aerial
vehicles (uavs) are better known as drones.
some drones fit in the palm of a hand. others look like a
small airplane. some are inexpensive toys. others cost
thousands, even millions, of dollars. they can be used for
everything from taking photos to delivering medicine or
fighting wildfires.

Explanation:

The text describes drones as unmanned aerial vehicles (UAVs). Among the options, "unmanned flying robots" aligns with the description of UAVs (drones) as they are robotic and fly without a human pilot on board. "Medicine delivery services" is a use case of drones, not the definition. "Small, inexpensive airplanes" is incorrect as drones can vary in size (some are small like toys, others can be larger and expensive) and their nature is that of robots (unmanned) rather than just being airplanes.

Answer:

unmanned flying robots
