单选题按照SOLAS的油船货油舱的隔离的要求：Cargo pump-rooms， cargo tanks， slop tanks and cofferdams shall be positioned forward of machinery spaces. However， oil fuel bunker tanks need not be forward of machinery spaces.

Pump-rooms containing pumps and their accessories for ballasting those spaces situated adjacent to cargo tanks and slop tanks and pumps for oil fuel transfer， shall be considered as equivalent to a cargo pump-room within the context of this regulation provided that such pump rooms have the same safety standard as that required for cargo pump-rooms.问：对于某29.7万载重吨的VLCC船型，关于货油舱的隔离，下列哪一项不必位于机器处所的前方：（）A
货油泵舱；B
货油舱；C
