A recent start-up company, which we will call Dronegistics, has developed an innovative unmanned aerial vehicle, or drone. The company plans to sell its drones to companies who would use them to make commercial deliveries within congested urban areas. Dronegistics has identified several markets in Asia as having high commercial potential. Japan and Singapore are perceived to have the strongest market potential currently, but mainland China, Thailand, and Malaysia are perceived to have strong and growing potential over time, even if their potential may not be as strong currently. Despite expectations that several other firms will introduce competitive products in the near future, which will have an impact on the attractiveness for later entrants, Dronegistics lacks the experience and resources to enter more than one Asian market at a time. The decision-making challenge facing Dronegistics incorporates all of the following location clocks associated with timing decisions EXCEPT the:

__a. firm clock.

__b. location clock.

__c. incentives clock.

__d. competitive clock.
