The type of vertical conflict from the options provided is disintermediation.
Vertical conflict typically occurs between different levels of the same channel, such as manufacturers and retailers. Disintermediation involves the removal of intermediaries (such as retailers or wholesalers) from the supply chain, which can create conflict between manufacturers and those intermediaries.
Customer dissatisfaction and exclusive distribution are more related to different concepts, while administered systems generally refer to governance within a channel rather than a conflict type.
