Explanations:

AWS Business Support provides technical support but does not offer the depth of guidance and support needed for operational readiness assessments and risk mitigation for product launches without additional charges.

AWS Basic Support offers no technical support or guidance, making it insufficient for assessing operational readiness or mitigating risks prior to a product launch.

AWS Developer Support is designed for developers and provides limited support for production workloads. It does not provide the comprehensive guidance necessary for operational readiness assessments at no additional charge.

AWS Enterprise Support offers proactive guidance, operational readiness assessments, and risk mitigation strategies without additional charges, making it ideal for preparing for a new product launch.
