Answer: By enabling API caching in API Gateway.
The correct answer is A: By enabling API caching in API Gateway. Enabling caching stores the responses from the API and returns them to subsequent requests without invoking the Lambda function each time. This reduces the number of calls to Lambda, thus improving API performance and reducing latency for users. Options B, C, and D do not specifically address improving the responsiveness of the APIs.
