D is likely the only one that you can get rid of immediately. It benefits you. It does not benefit the society in general.
A is subtly the same thing as D. If you make the economy grow, the first individual who will benefit from it is you. That statement is up for argument, because you could contribute to economic growth without benefitting yourself, but there are better answers.

B The answer is B. The "common good" does not need to involve money or government. It is simply doing what is right for everyone.
