Why might using a union with additional members to manage type safety lead to questionable utility?

Because it violates object-oriented principles
Due to memory allocation overhead
Because the data space savings might be offset by the space used for type management
Because it complicates code unnecessarily

The correct answer is: Because the data space savings might be offset by the space used for type management

Using a union with additional members may seem like a convenient solution for managing type safety, but it can actually result in questionable utility. While it may save some data space, this benefit can be offset by the space needed for type management. Additionally, using a union can make the code more complicated and harder to maintain. This option should be carefully considered and alternatives should be explored before implementing it. Therefore, option C is the most accurate answer.
