In AWS, a task definition is a blueprint that defines how to run a Docker container in a task. Each task definition consists of various parameters that define how the container should be launched and run.

To answer the question, the parameters specified in a task definition are as follows:

A. The Docker images to use with the containers in your task: This parameter specifies the Docker image that will be used to launch the container. It could be an image from a public or private Docker repository, or a custom image that you have created.

C. How much CPU and memory to use with each container: This parameter specifies the CPU and memory resources that each container in the task should be allocated. You can set limits on the maximum amount of CPU and memory that a container can use.

E. The command the container should run when it is started: This parameter specifies the command that should be executed when the container is started. This can be a simple command or a more complex script that runs multiple commands.

B, D are incorrect: B. EC2 instance types to be used as container instances: This parameter is not specified in a task definition. Instead, you would specify the instance types when you create a cluster of EC2 instances to use as container instances.

D. AWS VPC and subnets to launch containers in: This parameter is not specified in a task definition either. Instead, you would specify the VPC and subnets when you create a task or a service.

I hope this helps!
