A is the correct answer: updateView You should call the webAPI.retrieveMultipleRecords function in the updateView function of your custom Power Apps Component Framework (PCF) control. The updateView function is called whenever the control's view needs to be updated, such as when the record is loaded or the user interacts with the control.

The updateView function is called when the component is first loaded and rendered on the screen. This function can be used to retrieve data from the Dynamics 365 instance, such as the list of valid area codes, and set the initial state of the component. By calling webAPI.retrieveMultipleRecords in the updateView function, you can ensure that the list of valid area codes is available for the user to select from as soon as the contact record is opened. NotifyOutputChanged is used to notify the parent component that the value of the output property has changed and getOutputs is used to get the output property values.
