A development team uses AWS Elastic Beanstalk to deploy a Java-based web application. The team wants to ensure that the changes to the source code and the configuration are always deployed on new instances. The team configures the Elastic Beanstalk environment to use immutable updates. However, an error occurs the first time a change is deployed with the new update policy.
What is the MOST likely cause of this issue?

A. Immutable updates are not supported for Java-based applications.
B. The account has reached its on-demand instance limit.
C. Immutable updates are only supported for m4.large and larger instance types.
D. The developer must also modify the .ebextensions/immutable-updates.config file to enable immutable updates.
