Answer:
The frequency of congressional overrides of presidential vetoes has varied throughout history. However, the most common answer to this question is A. Rarely. This is because it takes a two-thirds vote of both the Senate and the House of Representatives to override a presidential veto, which can be difficult to achieve, especially if the president's party holds enough seats to sustain the veto. According to the Congressional Research Service, as of 2021, there have been 111 vetoed bills that Congress has overridden, out of more than 1,500 vetoes issued by presidents.
