Answer:
public: virtual void print()=0;
Explanation:
An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.
A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();
A pure virtual function declaration is followed by '=0;'

Answer:
Option A:
<input name="name" id="id" type="number" value="value" step="value" min="value" max="value" />
Explanation:
Spinner control is a graphical control element where user can adjust the value by pressing up or down arrow button. An example is given in the attached image.
In HTML, one of the key attributes we must use to create a spinner control is "step". The attribute "step" is required to specify the interval of the step value when user press the up or down arrow button.
If we set the attribute values as follows:
- type = "number"
- value = 2
- min = 0
- max = 10
The setting above will give a spinner control with a range of legal numbers between 0, 2, 4, 6, 8 and 10.
