Technician A is correct because a worn-out HID arc tube (bulb) can cause intermittent operation of the headlight. HID bulbs can fail in a way that allows them to work sporadically before they completely stop working. Technician B's suggestion of a blown fuse would not cause intermittent operation; if the fuse were blown, the headlight would not work at all.
