Suggested Answer: C 🗳️
Azure Blob Storage on IoT Edge provides a block blob and append blob storage solution at the edge. A blob storage module on your IoT Edge device behaves like an Azure blob service, except the blobs are stored locally on your IoT Edge device.
This e is useful where data needs to be stored locally until it can be processed or transferred to the cloud. This data can be videos, images, finance data, hospital data, or any other unstructured data.

I think you need to share more insights on why you think an answer is correct so you would help people gain more understanding. Just saying correct with no basis is not enough. Thanks.
