Question: What is the purpose of the ViewChild decorator in this component class?

1. It provides access from within the component class to the ElementRef object for the `

   ` tag that has the bio template reference variable in the component's template view.

2. It indicates that the `

   ` tag be rendered as a child of the parent view that uses this component.

3. It makes the `

   ` tag in the template support content projection.

4. It makes the `

   ` tag visible in the final render. If the #bio was used in the template and the @ViewChild was not used in the class, then Angular would automatically hide the `

   ` tag that has #bio on it.

Answer: The correct answer of the above question is Option A:It provides access from within the component class to the ElementRef object for the `

` tag that has the bio template reference variable in the component's template view.
