About Question enthuware.ocajp.i.v7.2.862 :

[SirZed]

The question is: Which of the following options when applied individually will change the Data object currently referred to by the variable d to contain 2, 2 as values for its data fields?

So the answer: Add the following statement: d = new Data(2, 3); is trivially incorrect, since it would set the values to 2 and 3.

You might wish to correct it, so it won't be so obvious.
