Explanation
True (A) is correct because the definition of a service-oriented solution places no minimum requirement on the number of services or service capabilities involved. A solution architecture qualifies as "service-oriented" based on how it is structured (using service principles), not how many services it contains - even a single service exposing a single capability can fulfill a business requirement in a valid SOA.
Option B is wrong because it falsely implies a minimum cardinality requirement that doesn't exist in SOA definitions. There is no rule mandating multiple services or multiple capabilities for a solution to be considered service-oriented.
Memory tip: Think of SOA like a vending machine - even one machine with one button is still a vending machine. Scale is irrelevant to classification; design principle is what matters.
