The code contained in the . . . . . . . . allows an application to retrieve the contents of the Private variable associated with the property.

The correct answer is: D. Getter Block

A getter block is a special type of method that is used to retrieve the value of a private variable. It is called a getter block because it gets the value of the variable. The code contained in the getter block is executed when the property is accessed.

A setter block is a special type of method that is used to set the value of a private variable. It is called a setter block because it sets the value of the variable. The code contained in the setter block is executed when the property is assigned a new value.

A retrieve block is not a valid term in programming.

A set block is not a valid term in programming.

Here is an example of a getter block:

public int getAge() {
return age;
}

In this example, the getAge() method is a getter block. It is used to retrieve the value of the age private variable.

Here is an example of a setter block:

public void setAge(int age) {
this.age = age;
}

In this example, the setAge() method is a setter block. It is used to set the value of the age private variable.
