In an attempt to address the national reaction to the pardon of former president nixon, president ford pardoned all watergate participants. revoked the pardon. testified before congress. invoked the power of executive privilege.

The correct answer here is that President Ford: Testified before Congress, after the matter with former President, Richard Nixon after the Watergate scandal.

Explanation:

One of the main criticisms that President Gerald Ford received after his short term in office, when he was defeated by Democratic candidate Jimmy Carter, in 1976, was the pardon he granted to former president, Richard Nixon, after the Watergate scandals. This criticism was gained because no one, not even his own supporters or colleagues, agreed to the motion and many believed it came from fraud, and deals between Ford and Nixon, who had shared a friendship and a working relationship when Nixon became president and Ford  became vice-president. On October 17, 1974, President Gerald Ford was called into Congress, specifically the House of Representatives, to render an explanation as to why he granted such a pardon to Nixon.
