Answers
D.
Call this.template.querySelector() passing an id
Suggested answer: A

Explanation:

In Lightning Web Components, to access the DOM elements within the component's template, including those passed into slots, developers use this.template.querySelector() and this.template.querySelectorAll(). These methods allow for querying the component's local DOM. Direct DOM manipulation or querying outside the component's template is discouraged to maintain component encapsulation and security. For more information, see the Salesforce LWC documentation on accessing the DOM: Salesforce LWC DOM Access Documentation.
