What organizational challenge does "you build it, you test it, you run it" (common in DevOps culture) address compared to traditional siloed QA teams, and what risk does it introduce if not balanced properly?

A It increases developer ownership and speeds feedback by removing handoffs to QA, but risks losing specialized testing expertise (deep exploratory or performance skills) if testing becomes an afterthought under deadlines B It eliminates the need for any testing whatsoever C It requires hiring a completely separate team for every microservice with no developer involvement D It guarantees zero production incidents with no further effort
