What must peace officers execute and file before performing their duties?

The correct answer emphasizes the requirement for peace officers to execute and file a written oath of office before they can officially perform their duties. This oath is a foundational aspect of the role of a peace officer, as it signifies their commitment to uphold the law and serve their community faithfully.

In Texas, peace officers are required to take this oath to ensure they understand and accept the ethical and legal obligations of their position. The process is crucial for maintaining public trust and accountability within law enforcement agencies.

While a good and sufficient bond may be associated with certain duties or positions within law enforcement, it is not the primary document that officers must complete before assuming their responsibilities. Other options, like mental health evaluations and certificates for training, may be beneficial or required at different points in a peace officer's career, but they do not replace the necessity of the written oath of office as a prerequisite for duty.
