The Seventh General Order of the Guard states, "To talk to no one except in the line of duty." This order emphasizes the importance of maintaining vigilance and discipline while on guard duty. The purpose of this directive is to ensure that guards remain focused on their responsibilities and are not distracted by conversations or activities that are not related to their duties. By refraining from engaging in conversation unless necessary for the performance of their duties, guards are better able to observe their environment and respond appropriately to any incidents or changes.

In contrast, the other options reflect different aspects of guard duty but do not correspond to the Seventh General Order. Saluting officers and colors, giving an alarm in case of fire, and challenging all persons on post are all critical components of a guard's responsibilities, but they fall under different general orders. Each order serves a distinct purpose, enhancing the overall effectiveness and security of the guarding process.
