Test class initiates the object. And call the start function, 'stra' stores 'do' and 'strb' waits for the value for returning method function. After the control moves to the method function(). And it concatenates the value of 'stra' and prints 'dogood'. Finally, the method returns a 'good' start function. 
∴ Hence the correct answer is dogood : do good.
