In discussing segregation, the IMDG Code defines what it means by the term "separated from". Which of the following is that definition?

Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable. For "on deck" stowage, this means a distance of at least 12 metres. This distance also applies to one package stowed "on deck" and another in an upper compartment.

With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable. For "on deck" stowage, this segregation means a distance of at least 12 metres irrespective of compartment divisions.

Effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident, but may be transported in the same compartment or hold or on deck, provided a horizontal separation, projected vertically, of 3 metres is obtained.

In different compartments or holds when stowed "under deck". Provided an intervening deck is resistent to fire and liquid, a vertical separation may be accepted as equivalent. For "on deck" stowage, this segregation means a distance of at least 6 metres.
