In the context of servo control, the instruction myservo.attach(9) connects a servo to which pin type?

The main idea is that the attach call designates which pin will output the servo’s control pulses. The control wire of a servo carries a timing signal that tells it where to move, not power or ground. The value given to attach is the digital pin number that will drive that signal, so directing it to pin 9 means the servo’s control wire should be connected to digital pin 9. This pin will generate the pulses the servo uses to set its angle, while the servo’s power and ground are provided separately. The other options describe ground connection, duration, or voltage, which aren’t how the control signal is sent.
