Select the most more appropriate option to fill in the blank.
The ruling party found itself in full ________ with the opposition.

accord

The most appropriate option to fill in the blank is accord.

The word "accord" means a state of agreement or harmony. In this context, it is the most accurate word to describe how the ruling party found itself in full agreement with the opposition. The ruling party and the opposition were in complete agreement on the issue at hand. They were not in discord or disagreement.

The other options are not as appropriate.

• Opinion means a belief or judgment that is not necessarily based on fact. It is not the best word to describe how the ruling party found itself in full agreement with the opposition because it does not capture the sense of harmony or agreement.
• Concord means agreement or harmony. It is a synonym of "accord" and is therefore also a good option to fill in the blank. However, "accord" is slightly more specific and is therefore the better choice.
• Discord means disagreement or conflict. It is not the best word to describe how the ruling party found itself in full agreement with the opposition because it does not capture the sense of harmony or agreement.
