For an e-commerce application, you have to implement a caching mechanism to reduce database load. Which GCP service would you use for caching, considering the data to be cached is key-value pairs and should be globally distributed?

*Explanation:* To implement a caching mechanism for an e-commerce application, especially for key-value pair data that needs to be globally distributed, the most suitable GCP service is **Cloud Memorystore for Redis**. Redis is a highly efficient and popular in-memory data store that excels at caching and provides low-latency access to data. It's ideal for reducing the load on your database and speeding up data retrieval. The other options (A, B, D, E) are not specifically designed for caching and may not provide the same level of performance and ease of use.
