Answer: (B)

Data view _UndeliverableSms focuses on SMS deliverability for MobileConnect. In Marketing Cloud, data views are read-only tables you can query to understand how messages perform across channels. _UndeliverableSms records each SMS that could not be delivered to a MobileConnect subscriber, including when it happened and the reason (such as an error code or description). This makes it the right source for troubleshooting why an SMS didn’t reach a recipient and for spotting patterns like opt-outs, invalid numbers, or carrier blocks. It isn’t about email unsubscribes (that would come from an email-specific view), survey responses, or journey status, which are tracked in different data views or systems.
