Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  The iOS update corrupted the app's data; reinstalling the app will fix it.

  Why it's wrong here

  While reinstalling an application can resolve issues stemming from corrupted local data or configuration files, an iOS update primarily introduces changes to the operating system's core frameworks and APIs. An older app's code, not designed to interact with these new system interfaces, is more likely to encounter an API incompatibility or unexpected system behavior, leading to a crash. Reinstallation would not update the app's underlying code to be compatible with the new iOS version.

• ✓

  The banking app is not compatible with the new iOS version and needs an update from the developer.

  Why this is correct

  Major iOS updates frequently introduce significant changes to system frameworks, deprecate older APIs, and modify security protocols. An older banking application, not yet updated by its developer, may attempt to call functions or interact with the operating system in a way that is no longer supported or has changed behavior in the new iOS version. This incompatibility often results in the application crashing immediately upon attempting a critical function like logging in, as it encounters unexpected system responses.

• ✗

  The user's account has been locked due to multiple failed login attempts.

  Why it's wrong here

  An account lockout is a server-side security measure implemented by the banking institution, not a client-side application crash. If a user's account were locked due to multiple failed login attempts, the banking app would typically successfully communicate with the server, receive an explicit error message (e.g., "Account Locked" or "Too Many Attempts"), and then display that message to the user. It would not cause the application itself to crash unexpectedly before or during the login attempt.

• ✗

  The iOS update changed the device's security settings, blocking the app.

  Why it's wrong here

  iOS security settings, such as app permissions, privacy controls, or enterprise profile restrictions, typically govern an application's ability to launch, access device features (like camera or location), or connect to networks. If security settings were blocking the app, it would likely fail to open at all, display a system-level permission prompt, or show a clear error indicating a restriction. A crash specifically during the login process within the app's interface points to an internal application issue rather than a blanket security block.
