The reason why Prince said he had no freedom to fight for is the fact that he was a slave, as stated in option 1 and further explained below.

<h3>Why can't Prince fight?</h3>

According to the passage we are analyzing here, Prince was a slave who belonged to William. His owner expect Prince to join him in battle, that is, to fight alongside him. However, Prince explains that he cannot do so.

The reason why Prince has "no freedom to fight for" is the fact that he was a slave. Prince could very well join William in battle, but what for? Why should he fight for freedom when he is denied it? How can a slave be asked to die for the freedom of white people when his own people are treated as possessions?

By saying so, Prince got William to free him. Apparently, that sentence was an eye-opener to his master, who only now realized the incoherence there is in asking a slave to fight for freedom.

With the information above in mind, we can select option 1 as the correct answer.

This is part of the missing passage which we need to answer this question:

"At the time he began his military service, William owned a slave like most of his peers. The slave, named Prince, would have been expected to join William and serve with him in battle. As they were preparing to leave, Prince told William, "I have no freedom to fight for, sir." Seeing the truth in this, William is reported to have freed Prince immediately. Today, we look back on history through a great fog of time, and with lenses clouded by our own modern values. Our Founding Fathers displayed admirable courage in crafting and signing such a brilliant claim to human liberty."
