The correct answer is D. Add a getter method for the actType attribute. For a Visualforce page to display the value of a non-property variable like actType in a custom controller, an explicit getter method must be defined for that variable.
Question
A developer created a Visualforce page and custom controller to display the account type field as shown below. Custom controller code:
Visualforce page snippet:
The value of the account type field is not being displayed correctly on the page. Assuming the custom controller is properly referenced on the Visualforce page, what should the developer do to correct the problem?

- BChange theAccount attribute to public.
- CAdd with sharing to the custom controller.
- DAdd a getter method for the actType attribute.

Why each option
For a Visualforce page to display the value of a non-property variable like `actType` in a custom controller, an explicit getter method must be defined for that variable.
Converting `theAccount.type` to a String is unnecessary; the issue is accessing the value of `actType`, not the data type of `theAccount.type`.
The `theAccount` attribute is already accessible if declared with `get; set;` or explicitly as `public`, and this change would not resolve the problem of `actType` not being displayed.
Adding `with sharing` to the custom controller affects record access based on the running user's permissions but does not determine whether a controller variable's value can be displayed on a Visualforce page.
Visualforce pages rely on getter methods to retrieve the values of properties from Apex controllers. If `actType` is declared as `public String actType;` without a `{get; set;}` declaration, it requires an explicit `public String getActType() { return this.actType; }` method for the Visualforce page to successfully read and display its value.
