   A startup is building a new API service that will be used by external partners. The traffic is expected to be low initially but could spike unpredictably. The startup has a small team and wants to focus on developing features rather than managing infrastructure. They are considering using a serverless platform. What is the most important trade-off they should consider?

   • AThe difficulty in debugging and monitoring serverless functions.
   • BThe lack of control over the underlying operating system and runtime environment.
   • CThe maximum execution time limit for a single function invocation.
