You are tasked with deploying a latency-sensitive application on GCP. The application makes API calls to various microservices. You also need to ensure that the application is cost-effective. What is the best approach to minimize latency while keeping costs down?

*Explanation: To minimize latency and keep costs down for a latency-sensitive application with API calls to microservices, the best approach is to **deploy the application and microservices on separate VPCs and use VPC peering for connectivity** (Option E). This approach reduces latency by ensuring direct connectivity between the application and microservices while keeping costs manageable. The other options either introduce latency or are less cost-effective for this specific scenario.*
