Which statement best describes the effect when a B arm signal is flashing?

Explanation:
A flashing B arm indicates clearance to proceed at the higher speed permitted for that route. The flashing pattern communicates an upgrade in the allowed speed, not a stop, not a malfunction, and not a claim about track occupancy staying the same. So the best way to describe it is that you may increase to the approved speed for the upcoming block. The other options don’t fit because a flashing B arm isn’t a stop signal, nor is it an indicator of malfunction or a statement about occupancy.
