Multiple choiceEasychapter-13-curatedpremiumfastapiroute-handlers
Answer and explanation
Correct answer
C. Keep the concern close to the data or API boundary that owns it instead of scattering it across unrelated helpers.
Why
Responsibility should follow ownership. When the concern lives near the right boundary, the system is easier to test and explain.
