Consider the following phenomena: 1. Light is affected by gravity. 2. The Universe is constantly expanding. 3. Matter warps its surrounding space-time. Which of the above is/are the prediction/predictions of Albert Einstein's General Theory of Relativity, often discussed in media?

Option (d) is correct because General Relativity defines gravity as the warping of space-time by matter (3), which directly results in the bending of light paths (1) and provides the mathematical framework for a non-static, expanding universe (2). Option (c) is the most tempting wrong choice because many associate the expanding universe solely with Edwin Hubble’s observations, yet the theoretical prediction first emerged from Einstein’s field equations. The core concept tested is the fundamental principles and observable cosmological consequences of the General Theory of Relativity.
