Correct Answer:

Explanation:
< button onclick= " process() " > Process < /button >
< script >
function process()
{
}
< /script >
The button must use the onclick attribute because the required action occurs when the user clicks the button.
The plain word click is an event name used in JavaScript event listeners, but it is not the correct inline HTML event-handler attribute. The value of the onclick attribute must be process() because the function must actually be invoked when the click event occurs. Using process alone only references the function name and does not call it in this inline markup context. this.process would attempt to reference a property on the current element, and javascript:process is not the correct handler expression. Inside the < script > block, the correct function declaration is function process(). This defines the named function that the button's onclick attribute calls. The final structure therefore connects the button event directly to the script function: when the user clicks Process, the browser runs process().

Correct Answer:

Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender.

Correct Answer:

Explanation:
First drop-down: datalist
Second drop-down: vehicles
Third drop-down: < /datalist >
The correct element is < datalist > because the interface requires a text input that provides selectable suggestions while still allowing the user to type. The < input > element uses list= " vehicles " , so it must be connected to a < datalist > element whose id is exactly vehicles. The id cannot be vehicle, because vehicle is already the input element's own identifier and does not match the value used by the list attribute. The < option
> elements inside the datalist define the suggested values: Motorcycle, Truck, Boat, Car, and Bicycle. ul, ol, and li are list-markup elements and do not create input suggestions. select would create a fixed dropdown list, but it would not match the editable input-with-suggestions behavior shown. The closing tag must match the opening datalist element, so the final selection is < /datalist > .
