What attributes correspond to the following characteristics: Loosely Coupled, Idempotent, and Service Contract?

An organization is categorizing their existing services against service characteristics to determine how ready each one might be for the catalog. Part of this effort involves looking at the following three attributes for each service characteristic: considerations, benefits, and tradeoffs.

What attributes correspond to the following characteristics: Loosely Coupled, Idempotent, and Service Contract?
A . Consideration: late or dynamic binding of services
Benefit: development and implementation cost reduction
Tradeoff: complexity grows as number of services increases
B . Consideration: late or dynamic binding of services
Benefit: improves reliability and scale
Tradeoff: high degree of cooperation and agreement of design standards and conventions
C . Consideration: standardized service contracts and metadata definitions
Benefit: improves reliability and scale
Tradeoff: complexity grows as number of services increases
D . Consideration: standardized service contracts and metadata definitions
Benefit: development and implementation cost reduction
Tradeoff: high degree of cooperation and agreement of design standards and conventions
