Answer:
d.Service
Step-by-step explanation:
Raven is not working with the product nor the production process ( in this case, the cooking of coconuts) Therefore, it is a service by that definition.
Also, Raven is engaged in how to provide comfort with the customer. That is, fix their issues to convert into a happy customer or at least, not dissatisfy. Also, this relates even more to a service than logistics or operations.
