Which solution will meet these requirements MOST cost-effectively?

1. A. Host a dynamic contact form page in Amazon Elastic Container Service (Amazon ECS) Set up Amazon Simple Email Service (Amazon SES) to connect to any third-party email provider.
2. B. Create an Amazon API Gateway endpoinl with an AWS Lambda backend that makes a call to Amazon Simple Email Service (Amazon SES)
3. C. Convert the static webpage to dynamic by deploying Amazon Ughtsail Use client-side scnpting to build the contact form Integrate the form with Amazon WorkMail
4. D. Create a Q micro Amazon EC2 instance Deploy a LAMP (Linux Apache MySQ
5. E. PHP/Perl/Python) stack to host the webpage Use client-side scripting to buiW the contact form Integrate the form with Amazon WorkMail

Correct Answer: D
Create a t2 micro Amazon EC2 instance. Deploy a LAMP (Linux Apache MySQL, PHP/Perl/Python) stack to host the webpage. Use client-side scripting to build the contact form. Integrate the form with Amazon WorkMail. This solution will provide the company with the necessary components to host the contact form page and integrate it with Amazon WorkMail at the lowest cost. Option A requires the use of Amazon ECS, which is more expensive than EC2, and Option B requires the use of Amazon API Gateway, which is also more expensive than EC2. Option C requires the use of Amazon Lightsail, which is more expensive than EC2.
