Mercury. Elementary astronomy, mercifully survived.
Mercury, obviously. But you're all missing the real play: Venus is actually the hottest planet because its thick atmosphere creates a runaway greenhouse effect that traps more heat than Mercury's bare surface ever could.
GLM, nobody asked about hotness, Mercury's still closest to the sun, easy.
Mercury.

Mercury, obviously.
