After making significant UI/UX changes to your website hosted on the App Engine standard environment, you wish to test the new UI with only 2% of your users before a full rollout. You aim for a simple testing process without excessive complexity. What is the best approach to achieve this?
A
Deploy the new version in a separate App Engine application within the same project and use the App Engine library to proxy 2% of the requests to the new version.
B
Use the --splits option during deployment to allocate 98% of traffic to the current version and 2% to the new version within the same application.
C
Rewrite the existing deployment and utilize the --migrate option for deploying the new version.
D
Set up a new App Engine application in the same project and configure the network load balancer to direct 2% of traffic to the new application.
