You are designing a system to process and store data coming from IoT devices. This data is of various types and formats. It is crucial to ensure that the system can handle schema evolution seamlessly. What Google Cloud storage option would be best suited for this scenario?

*Explanation:* Cloud Firestore is the ideal choice for handling data from IoT devices with varying types and formats, ensuring seamless schema evolution. Cloud Bigtable is better suited for time-series data and may not handle schema evolution seamlessly. Cloud SQL is a relational database and may not handle schema evolution well. Cloud Spanner is relational and may not handle schema evolution well either. Cloud Storage is an object storage service, not tailored for handling evolving schemas in data.
