I would say d tbh because it seems right
The correct answer is "protection".
In feudal society, a vassal was a person invested with a fief for which they had to povide services to a lord. First, a feudal contract was made, and under that contract, the lord was bound to provide the vassal with the fief, i.e. to provide protection and to do him justice in court. In return the Lord could demand the services which were attached to the fief, and these could include all kinds of services - military, administrative etc.
Thomas Jefferson, when writing the Declaration of Independence of the US used a fundamental Judeo-Christian concept. At the Declaration, Jefferson states that: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness...".
The Judeo-Christian concept of God-given rights (for example: every man is created equal; rights over life and liberty...) is a fundamental concept used by Thomas Jefferson as the core of the Declaration of Independence.
The wrongs that he accused them off was them being infidels who pillage and steal and assault women and destroy churches and similar things. He accused them of attacking Christians and Christianity and wanted to force them to leave out of areas that were Christian.
The groups that he excluded was old people, weak, women, and the clergy. He didn't want these groups to go because he didn't believe that they could be helpful in war. Also, priests had to stay in Europe and not go to war because they were needed for spreading religion.
The appeals that he used is appeal to their emotions and he appealed to his credibility to speak so. In Christianity, the pope is the person who was chosen by god so what he says is what the god wants to be said. He said that they would all go to heaven if they supported the crusades which they believed and considered to be words from god.
