The correct option is UploadFromFileAsync.

UploadFromFileAsync is the convenience method provided by the Azure Storage client libraries that accepts a local file path and uploads that file as a blob in the target container. It handles reading the file and performing the upload and the client libraries manage chunking and retries so it is appropriate for large file uploads.

PutBlockBlobAsync is not the correct high level method for uploading a local file because put block operations are low level and are used to upload individual blocks and then commit them, which requires manual block management.

CreateBlobAsync is not a standard SDK method for this purpose and SDKs normally create blobs by calling upload methods rather than a method with that name.

UploadBlobAsync may exist in some client APIs to upload content from a stream or binary data but it is not the direct convenience method that takes a file path, so it is not the best answer when the question specifically asks about uploading a local file.
