Question: 1 / 565

For the class 'Integer', how is operator& overloaded?

By returning the address of the object itself

The operator& cannot be meaningfully overloaded for the class 'Integer' since it does not have a logical application for bit operations. Options B and C involve modifying or returning the object itself which is not a valid approach for a logical operator. Therefore, the only plausible explanation is A where the address of the object itself is returned which aligns with the general usage of the operator for pointers.
