Answer- A, B and C.

If you see the below snapshot from the EC2 on-demand pricing page, you can see the different components that make up the pricing.

For more information on AWS EC2 On-Demand pricing, please refer to the below URL:

The cost of On-Demand EC2 instances in AWS is determined by several factors, including:

1. Instance Type: The instance type is the most important factor that affects the cost of an EC2 instance. Each instance type has different hardware configurations and computing capacity, and the cost of each instance type varies based on these factors.

2. Region: The region in which an EC2 instance is launched also affects its cost. The pricing of EC2 instances varies by region because of the differences in the underlying infrastructure costs in each region. Some regions may have higher costs due to higher power or real estate costs, for example.

3. AMI Type: An Amazon Machine Image (AMI) is a pre-configured virtual machine image that is used to create an EC2 instance. The cost of an EC2 instance can be affected by the AMI type selected because some AMIs may include additional software or services that can increase the cost of the instance.

In contrast, "Edge location" is not an attribute that determines the cost of an On-Demand EC2 instance. Edge locations are locations where Amazon CloudFront content delivery network (CDN) endpoints are located, and are not related to the pricing of EC2 instances.

In summary, the three attributes that determine the cost of On-Demand EC2 Instance are Instance Type, Region, and AMI Type.
