View Answer

Correct Answer: A — OFF

Explanation:

When the switch is ON in a Buck Boost converter, it creates a direct path from the input source to the inductor, which stores energy. The diode is reverse-biased during this phase (OFF state), blocking current flow to the output. When the switch turns OFF, the inductor discharges through the now forward-biased diode to supply the load.
