The option that accurately describes how the Watergate scandal activated the system of checks and balances is: The legislative and judicial branches of government successfully checked the power of the executive branch.

During the Watergate scandal, the media, Congress, and the judiciary played a prominent role in holding the executive branch accountable for its corruption and abuses of power. The investigative reporting of journalists, the hearings of congressional committees, and the rulings of the Supreme Court all contributed to the exposure of the wrongdoing of the Nixon administration and its ultimate downfall. This is a prime example of how the system of checks and balances worked effectively, as each branch of government served as a check on the power of the others.
