Option C is the correct answer. By changing /product-details to perform the requests in parallel, you can reduce the time it takes for the request to complete by making multiple requests at the same time rather than sequentially. This will allow you to retrieve the information for all four products more quickly. Option A is not a good solution because increasing the size of the instance class may not necessarily reduce the time it takes for the request to complete. Option B is not a good solution because changing the Persistent Disk type to SSD will not have any impact on the time it takes for the request to complete. Option D is not a good solution because storing the /sku-details information in a database and replacing the webservice call with a database query will not necessarily reduce the time it takes for the request to complete, and it will add unnecessary complexity to the application.

App Engine is serverless so A and B are eliminated Between C and D, I'd take C. https://cloud.google.com/appengine/docs/standard/java/datastore/queries: "This solution is no longer recommended"

On 2nd thought, App Engine has instance classes: https://cloud.google.com/appengine/docs/standard So I'll change my answer to A

Pardon my fickle-mindedness Back to C as options A & B are wrong as they do not have a direct correlation with the issue and there is nothing to suggest they need to be increased.
