Correct Answer: C
The code demonstrates the difference between passing objects and primitive values in Java. In Java, objects (like 'Product' here) are passed by reference, meaning changes to the object's properties remain after the method call. On the other hand, primitive data types (like 'double' here) are passed by value, meaning changes to the variable inside the method do not affect the original value. Within the 'updatePrice' method, 'price' is a local variable and multiplying it by 2 doesn't affect the original 'newPrice' value. However, 'product.price' is updated through its reference. Initially, 'product.price' is 200. After calling 'updatePrice', 'product.price'+price' becomes 200+200 = 400. Therefore, the output is 'product.price: 400.0' and 'newPrice: 100.0', resulting in '400.0 : 100.0'.
