Correct Answer: Option (D) — 1, 2 and 3

Concept & Option Breakdown

Standard Reference Verified

Statement 1 is correct: General Relativity predicts gravitational lensing—the path of light rays bends when passing through the curved spacetime created by massive objects.

Statement 2 is correct: Einstein's field equations led to cosmological models (developed by Friedmann and Lemaître) predicting a non-static, expanding universe.

Statement 3 is correct: A fundamental principle of General Relativity is that mass and energy warp the surrounding four-dimensional spacetime, dictating the motion of matter and radiation.

Elimination Heuristic & Exam Approach

All three statements represent fundamental core tenets/consequences derived from Einstein's General Theory of Relativity.
