What feature allows Mr. Garcia to receive updates when new content is uploaded to a relevant YouTube channel?

The correct answer is subscriptions and notifications because this feature directly enables users like Mr. Garcia to stay informed about new content posted by channels they are interested in. When a user subscribes to a YouTube channel, they not only show their interest in the channel’s content but also gain access to notifications. These notifications can be customized, allowing users to receive alerts whenever new videos are uploaded or when there are updates from the channel. This makes it easy for Mr. Garcia to keep up with relevant channels without having to manually search for new uploads, ensuring that he never misses out on content that matters to him.

The other options, such as video recommendations, channel alerts, and video alerts, do not directly pertain to the specific action of receiving updates from subscribed channels. Video recommendations are typically suggested based on a user's viewing history, while channel and video alerts are not standard features recognized by YouTube in the same way subscriptions and notifications are, making the latter the most comprehensive and appropriate choice.
