Which observation directly confirms the equivalence principle governing gravity?

💡 Explanation

Gravitational lensing, or bending starlight, confirms the equivalence principle because gravity's effect on photons is equivalent to accelerated motion warping spacetime. Wavelight propagation exhibits that curve, showing that the shortest path will no longer be a straight line; therefore confirming A rather than any flat-spacetime prediction.
