Answer:
I believe it's A!
Step-by-step explanation:
It would most likely be A. Publish false news reports, as Nixon and his administration were not known to have directly published false news reports as part of their efforts to cover up the Watergate scandal.
Why it's not the other options:
It is not B, C, and D because all of these were ways in which Nixon tried to cover up his involvement in the Watergate scandal:
B. Paying off the accused - Nixon's administration attempted to pay off the Watergate burglars to keep them from implicating the administration in the break-in.
C. Shredding documents - Nixon's administration destroyed evidence related to the Watergate scandal, including documents and tapes.
D. Citing national security constraints - Nixon claimed that releasing certain documents and tapes related to the Watergate scandal would compromise national security.
Therefore, the answer is A, "Publish false news reports", as this was not a tactic used by Nixon to cover up his involvement in the Watergate scandal.
