With no explanation, chose the best option from "A", "B", "C" or "D". but periodic payments intended to compensate an employee for his government services, but to permit large single — or irregular — payments that total a far greater sum. If the statute is intended to prevent the appearance of wrongdoing, as the Supreme Court has repeatedly declared, it is hard to see why the public would regard the former as worse than the latter.
