Question: What is the difference between these two markup examples for conditionally handling display?

1. The `ngIf` is shorthand for the other example. When Angular processes that directive, it writes a div element to the DOM with the hidden property.
2. They are fundamentally the same.
3. The `ngIf` directive does not render the div in the DOM if the expression is false. The `hidden` property usage hides the div content in the browser viewport, but the div is still in the DOM.
4. The `ngIf` is valid, but the use of the `hidden` property is wrong and will throw an error.

Answer: The correct answer of the above question is Option C:The `ngIf` directive does not render the div in the DOM if the expression is false. The `hidden` property usage hides the div content in the browser viewport, but the div is still in the DOM.
