An instance of an abstract class can be created using (points : 2) the new operator
encapsulation
a public accessor
none of the above

The correct answer for the given question is the new operator.

Explanation:

An abstract class is those which have the only declaration of the abstract method, not a definition. Any class which inherits abstract class must define all the method of abstract otherwise it also be abstract.

To declared any abstract class following syntax is used  

abstract class class name

{

// abstract method  

}

To create an instance of an abstract class we can use a new keyword. The new keyword created the instance of an abstract class.

encapsulation is the feature of object-oriented we cannot create an object by using encapsulation so this option is wrong.

The public is an access modifier we cannot create an object by using public keyword so this option is also wrong.

Therefore the correct answer is new.
