The idea here is to identify a statement that includes both items in one assertion. To show that both 72 ISRS and 75 ISRS are included, you need a description that mentions both together. The line that says “Both 72 ISRS and 75 ISRS” does exactly that, signaling the inclusion of both. The other choices refer to only one of them (or to something unrelated), so they don’t convey the idea of both together. So the statement that explicitly mentions both items is the one that fits.

Understanding long-term sustainment and maintenance burden helps explain this item. The capability that signals you will need the least ongoing work to keep things running is low maintenance. When a system is described as low maintenance, it implies simpler upkeep, fewer required service actions, and, often, automation that reduces manual intervention. That directly indicates minimal ongoing maintenance, which is exactly what the question is asking about. High service quality speaks to how well the system performs, but it doesn’t specify how much maintenance is needed to keep that performance over time. Availability measures uptime, showing how often the system is operational, but not the maintenance workload required to sustain it. Multicast describes a method for distributing data, not the ongoing maintenance demands of the system.

The key idea here is understanding how command authority is scoped. Operational control gives a commander the right to organize and employ forces to accomplish assigned missions. That means you can group units, assign tasks, and direct how they work together to achieve the objective within the mission’s scope. It also allows reallocating forces as needed to meet the mission, without stepping into administrative details or into directing other commands. Tactical control is more limited: it covers directing the execution of specified actions within an operation, not broad organization of forces across missions. Administrative control handles admin and logistics, not the actual employment of forces in combat. The other term isn’t a standard authority for command-and-control. So, the term denoting the authority to organize and employ forces is operational control.

Tactical Control governs directing the execution of tactical operations, specifically how units are tasked, move, and maneuver to achieve a mission on the battlefield (or in-space equivalents). This scope means TACON lets a commander green-light the actual movements and coordinated actions of forces, without giving authority over longer-term planning or support functions. That’s why the option describing tactical tasking, movement, and maneuver is the best fit. Strategic planning belongs to higher-level decision-making about objectives and overall approach, not the day-to-day execution of actions. Administrative control covers personnel, administration, and some support duties, which are outside TACON’s focus. Logistics and sustainment deal with supply and maintenance, again outside the direct tactical execution authority TACON provides.
