b. RoboBug

c. RoboInsect

d. None of the above

ANSWER: RoboBee

Explanation:

For the first time, scientists have designed RoboBee, an insect like robot smaller than paperclip which can fly and swim. Scientists designed the robot using the puffin as a model. This micro robot smaller than a paperclip flies and hovers like an insect, flapping its tiny, nearly invisible wings 120 times per second. RoboBee is so small it cannot penetrate the surface tension of water.
