To create an order template class object named backorder and assign 0 as the
argument to the constructor, the proper syntax is

a. order backorder = 0;

b. order backorder = 0;

c. order backorder(0);

d. order backorder(0);

The answer to this question is option c

Explanation:

In this question the correct is option c because, In the java when we create the object of the class. The default constructor will automatically call and it doesn't take any arguments. But In this question we use the parameterized constructor because it take the argument and the correct way for assign the is Order (backOrder(0);) that is option C.
