Which tanker classification is described as carrying flammable liquids, class B poisons, and liquid food products with 4 psi vapor pressure?

Explanation:
Vapor pressure sets the tanker type: a cargo with 4 psi vapor pressure is handled by a low‑pressure liquid cargo tank. The designation MC306/DOT406 corresponds to that low‑pressure class, designed to haul flammable liquids, Class B poisons, and liquid foods that meet the 4 psi limit. The other tank types have different pressure ratings or cargo compatibility, so they don’t match the combination described.
