Answer C is correct.
According to AWD Developer support doesn't support API calls, Business, Ent on Ramp and EMT does,
https://aws.amazon.com/premiumsupport/plans/
Developer Support DOES NOT allow you to interact with AWS Support using API calls. The Developer plan provides access to AWS Support through email only.
The key point of the question is "most cost-effective."
Developer Support (B) costs only $29/month and provides API access to AWS Support, making it the cheapest option.
Business Support (C) costs at least $100/month—while it offers faster response times, it incurs additional costs just for API access.
Both plans support API access, but Developer Support is more affordable.
If API access is the only requirement, there is no need to choose a more expensive plan.
Business Support is suitable for enterprises that need 24/7 support and faster response times, but that is not what the question is asking for in terms of the "most cost-effective" option
In addition, customers with a Business, Enterprise On-Ramp, or Enterprise Support plan have access to these features:
Use-case guidance – What AWS products, features, and services to use to best support your specific needs.
AWS Trusted Advisor – A feature of AWS Support, which inspects customer environments and identifies opportunities to save money, close security gaps, and improve system reliability and performance. You can access all Trusted Advisor checks.
The AWS Support API to interact with Support Center and Trusted Advisor. You can use the AWS Support API to automate support case management and Trusted Advisor operations.
Based on https://aws.amazon.com/premiumsupport/plans/
"Programmatic Case Management" row
- "Developer" column - empty
- "Business" column - "AWS Support API"
AWS Developer Support includes access to the AWS Support API, which allows users to interact with AWS Support programmatically. This plan provides basic support features and is designed for users who are exploring AWS services or developing applications on AWS. It offers a more cost-effective option compared to higher-tier plans while still providing API access for support interactions.
AWS Business Support (option C): This plan provides more comprehensive support, including access to the AWS Support API and faster response times. However, it is more expensive than Developer Support and may be more than what is needed for a new user who requires only API access.
