Final answer:
The code that does not belong in the "task autonomous()" section of a VEX Robotics competition is VEXnet Remote Arm control, as human-controlled operation isn't allowed in the autonomous phase. So, the correct option is D.
Step-by-step explanation:
The code that does not belong in the "task autonomous()" section is VEXnet Remote Arm control. This section is meant for the autonomous period of a VEX Robotics competition where the robot performs tasks based on pre-programmed instructions without any human intervention. Thus, options like Forward until Near, Gyro-Turn, and Reset Encoder are valid as they involve autonomous navigation and sensor resets. However, the VEXnet Remote Arm control implies remote control operation, which is not part of the autonomous phase. During the autonomous period, the robot is not controlled remotely and should operate solely based on its programming.
For example, the code for 'Forward until Near' might use sensor input to move the robot forward until it detects an object nearby. The code for 'Gyro-Turn' might use a gyroscope to determine the robot's orientation and make a precise turn. And 'Reset Encoder' might reset the value of an encoder to start measuring a new distance. These are all actions that can be programmed to occur without manual intervention.
