Which circuit breaker is described as retracted and uses a knob to manually pull when necessary?

Explanation:
This describes a push-pull circuit breaker. In this type, the breaker sits retracted in the panel and a knob is available to manually pull the breaker out to disconnect the circuit when needed. To restore power, you push the knob back in. This manual pull mechanism distinguishes it from other breakers that reset by pushing, rather than pulling. The other options aren’t circuit breakers with a pull-knob design: a push-to-reset type requires a push to reset after tripping, while a rotary selector and relays are different kinds of switching devices rather than pull-out breakers.
