B is ok

B is ok. https://cloud.google.com/appengine/docs/the-appengine-environments

Both B and D are okay, however, the need for App engine Flexible environment is not required unless you want to run docker containers, have more control over the instance used and so on, hence in this case B works well. https://cloud.google.com/appengine/docs/the-appengine-environments

A GKE is much reliable compared to the other options provided here.

B is correct. It supports Go 1.12, and can handle sudden spikes. https://cloud.google.com/appengine/docs/the-appengine-environments

Can someone explain why we cannot use AppEngine Flexible environment ?

App engine standard provides go env.

App Engine Std. Can run this Go version and Scales to 0.

Standard AppEngine Environment supports Go 1.2. The AppEngine can be low cost if no or low traffic. It has free quotas.

AppEngine scales well, only dev effort. No infrastructure. go is supported in the standard distribution.

The answer is A. B option is not correct. It is not recommended to use App Engine Standard environment for an HTTP(S) API with a very unpredictable workload because App Engine Standard environment has certain limitations and constraints that may not be suitable for an API with an unpredictable workload. For example, App Engine Standard environment has a maximum request timeout of 60 seconds, which may not be sufficient for an API with a very unpredictable workload.

B is ok

B is correct ..https://cloud.google.com/appengine/docs/the-appengine-environments Experiences sudden and extreme spikes of traffic which require immediate scaling.

https://cloud.google.com/appengine/docs/the-appengine-environments App engine standard environment support go 1.13 and also handles the unpredictable load.

B. Unpredictable traffic & low overhead.

App Engine standard has autoscaling out of the box, supports Go 1.12 and can scale down to 0 to save money

B is ok.
