Adobe Exam AD0-E717 Topic 8 Question 38 Discussion

To add an image icon in front of the telephone field in the shipping address form on the checkout page, the correct way is to modify the UI component by setting a custom template file for the field. The snippet in option B is the correct one because it uses the <block> element and sets the elementTmpl to the custom template path within the arguments node under the config node. This modification will instruct Magento to use the specified custom template file for rendering the telephone field, allowing for the addition of an image icon in front of it.
