What is the primary purpose of iOS updates?

The primary purpose of iOS updates is to improve performance, add new features, and enhance security and privacy. Each update is designed to enhance the overall user experience by making the system run more efficiently, introducing new functionalities that can be beneficial to users, and providing critical security updates that protect devices from vulnerabilities and threats.

By regularly updating the iOS, Apple ensures that users have access to the latest enhancements, such as improved battery life, new applications, and better integration with other Apple services, while also safeguarding their data through updated privacy measures. This comprehensive approach means that users enjoy a more secure, feature-rich, and responsive device.

Changing the user interface completely is not a common goal for updates, as such changes might confuse users and require a significant adjustment period. Similarly, limiting app functionalities would not typically align with Apple's objectives; instead, updates generally aim to enhance functionality. Lastly, introducing new hardware options is often not related to the software updates but rather pertains to newer product releases. Overall, option C encapsulates the true intention behind iOS updates effectively.
