    Going from solid to liquid requires the addition of heat, which makes ΔH positive, so answer B.

    ("C6H6(s) → C6H6(l)" is no kind of reaction. It is a physical change in state.)

    You can't measure the enthalpy (H) of a substance, only the change in enthalpy (ΔH). Your answer choices need "deltas."
