The correct answer is D. Congress overrides a presidential veto of a law that establishes a new tax.
Explanation
The principle of checks and balances is a principle of government (constitutional) in which it is established that the branches of the public power (judicial, executive, and legislative) have the right and the duty to act to avoid actions of other branches to power is balanced between the three branches. According to the above, the correct answer is D. Congress overrides a presidential veto of a law that establishes a new tax because it illustrates a situation in which the branch of the legislature (Congress) avoids an action by the branch of the executive branch (president).
A taping system (aka recording device) installed in the office of the President helped lead to the downfall of President Nixon. While Nixon was president, a recording device was installed in his office to record phone and in-person conversations. When being accused of having ties to the Watergate break-in, the Supreme Court ruled that Nixon must release his taped conversations. These conversations had incriminating evidence and showed Nixon's true intent as president. Ultimately, the evidence discovered by these recorded conversations lead to Nixon's resignation.
The ensuing Mexican–American War was waged from 1846 to 1848 with the loss of many thousands of lives and the loss to Mexico of all of its northern provinces.
