Which of the following is not an advantage of robots?

Question

UnlockIAS · Accepted Answer

Correct — B, 'They can replace jobs.' Robots do replace human labour in many tasks, but this is consistently framed as a disadvantage or societal challenge of automation — job/livelihood displacement — not a benefit of using robots, unlike options A, C and D, which are all genuine advantages.

Why the other options are wrong — (a) This IS a genuine advantage of robots — e.g., robotic prosthetics, mobility aids and assistive exoskeletons — so it does not fit the 'NOT an advantage' criterion the question asks for.  (c) This is a genuine advantage — bomb disposal, nuclear facilities, and deep-sea or space exploration are classic cases where robots protect human life by taking on hazardous work.  (d) This is a genuine advantage — robots can run continuously without fatigue, boosting productivity, unlike human workers who need rest.

Concept: Robots are automated machines valued for consistent, tireless operation, precision, and the ability to work in environments unsafe for humans. These strengths are genuine 'advantages' of using robots. Job displacement — robots replacing human workers — is a real consequence of automation, but it is framed as a societal cost/disadvantage (a challenge for labour markets and livelihoods), not a benefit of the robot itself.
