A developer wrote the following two classes: The StatusFetcher class successfully compiled and saved. However, the Calculator class has a compile time error. How should the developer fix this code?

Changing the class declaration to `public with inherited sharing` controls record sharing context, which is unrelated to the compile-time error caused by insufficient method visibility between classes.

For the Calculator class to invoke the `isActive()` method of the StatusFetcher class, the `isActive()` method must be declared with the `public` access modifier, allowing it to be visible and callable from other classes. By default, methods without an explicit access modifier are private.

Making the `doCalculations` method private would restrict access to `doCalculations` itself but would not resolve the compile-time error occurring within `doCalculations` when attempting to call an inaccessible method from StatusFetcher.

Changing the Calculator class declaration to `public with inherited sharing` controls record sharing, which does not address the method accessibility issue between the two classes.
