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

@Component({
    ...
    template: '<p #bio></p>'
})
export class UserDetailsComponent {
    @ViewChild('bio') bio;
}

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.

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

It makes the  tag in the template support content projection.

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.
