Option 3:

Answer 1

[(ngModule)] = "attrname" is a two-way binding used in Angular to bind a model property to a template attribute.

Step-by-step explanation:

The subject of this question is Computers and Technology and the grade level is High School.

1. The correct option is Option 1: It binds a model property to a template attribute. Two-way binding [(ngModule)] = "attrname" allows data to flow in both directions, enabling changes in the template attribute to update the model property and vice versa.
2. Option 2 is incorrect. One-way data binding is represented by [(ngModel)] = "attrname", where changes in the template attribute update the model property, but changes in the model property do not affect the template attribute.
3. Option 3 is incorrect. [(ngModule)] = "attrname" does not define a module in Angular.
4. Option 4 is incorrect. [(ngModule)] = "attrname" is a valid Angular syntax.
