To enable the use of Spot Instances for an Elastic Beanstalk environment, it is necessary to configure the setting that specifically allows for Spot Instances by assigning it a value that indicates activation. The correct configuration is "AWS:EC2:Instances.EnableSpot = true." This setting directly instructs Elastic Beanstalk to utilize Spot Instances when launching the EC2 instances in the environment.

Using true as a value indicates that Spot Instances can be requested, allowing for cost savings and flexibility in resource usage. Spot Instances are often sold at significantly lower prices compared to On-Demand Instances, making them an attractive choice for many applications, particularly those that are fault-tolerant or can handle interruptions.

The other configurations reflect either non-standard syntax or incorrect values that would not allow for the activation of Spot Instances. Options that use terms like "enabled" or "on" do not align with the standardized True/False or Boolean configuration required by Elastic Beanstalk for this setting. Thus, the correct option effectively communicates the intention to use Spot Instances within the environment.
