You read a headline that states, "bill vetoed; veto overridden." which branches of government would have been involved in this process? (3 points) congress passed the bill; the president vetoed it. congress vetoed the bill; the president put it into law anyway. the president put a bill into law; congress voted to override. the president vetoed the bill; congress voted to override.

The president vetoed the bill; Congress voted to override.

A wouldn't make sense, because then the headline would just be "bill vetoed".
B wouldn't make sense, because Congress can't veto bills, and the President can't just pass laws as he likes, because that would make him too powerful (which is why we have checks and balances).
C doesn't make sense because again, that's not how the process works.

The congress completes the diagram
