no need to have it from both of them, questions from
only one are sufficient I think.

Each credit card service provider has its own interface
that all client programs must use. What is the BEST
way to design a system so that it may easily switch
between multiple providers and add new providers as
required, while keeping the complexity low.
A. Create an object with a common API for business
objects to use. This object covers all credit card
providers and routes requests from the business objects
to the adaptor object of the designated credit card
service provider, which handles the interface conversions.
B. Create an ordered collection of credit card service
providers and have each try to handle the service
requests from the business objects. If one cannot
handle the request it passes the request to the next
one until it is eventually handled or discarded.
C. Have the business objects communicate directly
to the service providers using each service provider's
D. Maintain a global pool of credit card service requests
from the business objects. Each credit card service
goes through the pool to find and claim the requests
that it can handle. It then processes each request.
