You are developing a short-term image hosting service where end users around the world can upload images that are up to 20MB, and the images will be automatically deleted after 10 days. You need to determine how the images should be stored while minimizing cost. How should you store the images?

A. Write the image to a Cloud Storage bucket. Create a lifecycle configuration that deletes objects 10 days older than their creation date. B. Write the images to Spanner. Configure a row deletion policy on the table that deletes rows 10 days older than their creation date. C. Write the images to Firestore. Deploy a Cloud Scheduler-invoked Cloud Run service that queries for documents written 10 days prior to today and deletes them. D. Write the images to Bigtable. Configure a garbage collection policy for the column family that deletes cells 10 days older than their creation date.
