B

MCQ: Einstein's mass-energy relationship states that if mass decreases by Δm, energy released ΔE is given by

- ΔE = Δm × c, where "c" denotes the speed of light.
- ΔE = Δm × c², where "c" denotes the speed of light.
- ΔE = Δm ⁄ c, where "c" denotes the speed of light.
- ΔE = Δm ⁄ c², where "c" denotes the speed of light.
