Answer - B.
The AWS Documentation mentions the following.
The EB CLI is a command-line interface for Elastic Beanstalk that provides interactive commands that simplify creating, updating and monitoring environments from a local repository.
Use the EB CLI as part of your everyday development and testing cycle as an alternative to the AWS Management Console.
Because of what the AWS Documentation mentions, all other options are invalid.

The BEST way to ensure that developers can work with Elastic Beanstalk environments without giving them access to the AWS Console is to ask them to manage the environments via the Elastic Beanstalk Command Line Interface (EB CLI).
The EB CLI is a command-line tool that simplifies the process of deploying, managing, and scaling applications in Elastic Beanstalk environments. It provides a set of commands that developers can use to interact with their applications, such as deploying new versions, viewing logs, and scaling instances.
By using the EB CLI, developers can work with Elastic Beanstalk environments from their local development environments, without the need to access the AWS Console. They can also use their preferred programming languages and tools to manage the environments, as the EB CLI supports multiple languages and platforms.
Option A, asking developers to manage the environments via the SDK, is also a valid solution. However, it requires developers to write code to interact with Elastic Beanstalk, which may not be as straightforward as using the EB CLI. Additionally, developers may need to authenticate their requests to the AWS API, which can add complexity to the solution.
Options C and D, asking developers to manage the environments via an EC2 instance or an ECS cluster, are not ideal solutions for this scenario. Both options require developers to have access to AWS resources, which goes against the requirement of not giving them access to the AWS Console. Additionally, managing Elastic Beanstalk environments through an EC2 instance or an ECS cluster can add unnecessary complexity to the solution.
Therefore, the BEST solution for this scenario is to ask developers to manage the environments via the Elastic Beanstalk Command Line Interface (EB CLI)
