Answer:
The people are willing participants in the trials.
Step-by-step explanation:
Frank R. Stockton's short story The Lady, or The Tiger revolves around a certain kingdom with a barbaric custom of executing a 'fair trial' that involves the convicted person to chose between two choices. These two choices will determine his/her future, which, no one can object to, considering the choice was made by that person alone.
In the given excerpt from the story, the narrator reveals that the "trial" was indeed supported by the people. Not only did they agree that the accused person chose his own fate but it also gave them entertainment. The very fact that the outcome is the decision of the accused is what makes the trial "fair" which they cannot object to.
Thus, the correct answer is the third option.
