What iOS feature is directly related to sharing contacts?

The selected answer is directly related to how iOS facilitates the sharing of contacts. In iOS, users can easily share their contacts through various means, such as email or text messages. This feature allows for seamless communication, enabling individuals to quickly pass along contact information to others without needing to manually enter details.

Sharing contacts via email or text is user-friendly and provides a straightforward way to connect with others, ensuring that essential contact details are transmitted securely and efficiently. This capability is particularly useful in both personal and professional contexts, where sharing contact information swiftly can enhance communication and collaboration.

While other options touch on aspects of connectivity or data management, they do not specifically address the direct action of sharing contacts. For instance, social networking may involve contact connections but does not focus on the act of sharing individual contact details. iCloud Integration facilitates backup and synchronization of contacts but isn't an immediate function for sharing them. Similarly, device backup pertains to data preservation and is unrelated to the direct sharing of contact information.
