Explanation:
App Engine has a request size limit of 32MB in the standard environment. To handle a 500MB file upload, using signed URLs (Option C) allows clients to upload files directly to Google Cloud Storage (GCS), bypassing App Engine's request size limitation. This approach offloads the upload process to GCS, which supports large files. Options A (FTP) and B (CPanel) are not supported by App Engine. Option D (multipart upload) does not resolve the 32MB request size constraint, as the total request size (including all parts) would still exceed the limit.
