The correct answer is Cloud Storage, which is designed specifically for storing and retrieving any amount of data at any time. It provides a highly scalable and durable infrastructure to store files and documents, making it suitable for various use cases such as backups, static website hosting, or serving large data files.

Cloud Storage allows users to upload and access various types of files, from images and videos to documents, with ease. It is also cost-effective, with pricing based on the amount of data stored and accessed, which provides flexibility for businesses that require dynamic scaling of storage based on their needs.

Other services like Google Cloud Firestore are more focused on NoSQL databases for structured data, while BigQuery is intended for data warehousing and analytics rather than file storage. Cloud Spanner is a relational database service designed for high availability and scalability, but again, it does not serve the purpose of flexible document and file storage the way Cloud Storage does. Thus, Cloud Storage stands out as the best fit for flexible and scalable file and document storage in Google Cloud.
