the answer is A. because the robotic arms are controlled by instruments similar to joysticks that the surgeon controls.
When you play a video game, you move a control button, and the machine translates your movements into real-time, mimicking your moves precisely on the screen. During a Robotic-assisted procedure, your surgeon uses master controls to manipulate the instruments, and the instruments translate your surgeon’s movements into precise movements inside your body. Your surgeon is in control the whole time; the surgical system responds to the direction he provides.
