Final answer:
The maximum limit for message visibility is 24 hours, after which messages are automatically removed or deleted.
Step-by-step explanation:
The maximum limit for message visibility depends on the platform or application being used. However, based on the options provided, the correct answer is D. 24 hours. This means that messages sent will remain visible for a maximum of 24 hours before being automatically removed or deleted.
For example, on some messaging apps or social media platforms, messages may have a default visibility duration of 24 hours, after which they will no longer be visible to the recipient or in the conversation. This feature is often used for temporary or ephemeral messaging, where messages are meant to be seen only for a limited time.
It's important to note that different platforms or applications may have different settings or options for message visibility. Some platforms may allow users to change or customize the visibility duration, while others may have a shorter or longer default duration.
