D) Pluto

Quizplus · Accepted Answer

Miranda has the lowest escape velocity among the options given. Escape velocity is determined by the mass and radius of the celestial body, and Miranda, being one of the smallest and least massive moons in the solar system, would naturally have a lower escape velocity compared to larger bodies like Ganymede, Triton, and Pluto.
