Which is Einstein's famous equation?

Answer and explanation

Correct answer: E = mc²

The correct answer is B, E = mc². This equation expresses mass–energy equivalence: energy E is related to mass m, and c represents the speed of light in a vacuum. Because the speed of light is squared, even a small amount of mass corresponds to a very large amount of energy. The other formulas are genuine scientific relations, but they belong to different contexts. F = ma is Newton’s second law of motion, V = IR is Ohm’s law, and A = πr² gives the area of a circle. Their authenticity makes them plausible distractors, yet none is identified with Einstein in this question. Hence option B is the only correct choice.
