Official UPSC Answer KeyUPSC Prelims 2019 • Science and Technology

Correct Answer: Option (B) — 3 and 4

Concept & Option Breakdown

Standard Reference Verified

Statement 1 is incorrect & Statement 3 is correct: Augmented Reality (AR) superimposes computer-generated digital assets (such as graphics, text, or 3D models) onto the user's real-world environment via cameras on devices like smartphones, tablets, or AR smart glasses without shutting out the physical world.

Statement 2 is incorrect & Statement 4 is correct: Virtual Reality (VR) replaces the physical environment entirely with a computer-simulated digital environment, isolating the user from external physical surroundings via head-mounted displays (HMDs) to deliver an immersive experience.

Elimination Heuristic & Exam Approach

Concept inversion: The UPSC question intentionally swapped the definitions of AR and VR in Statements 1 and 2. Statements 3 and 4 provide the correct respective definitions.
