The correct answer is C) the erase signal then continue the message with the last correctly spelled word. This is the correct action because if you make an error while signaling by flashing light, you should use the erase signal (VE) to indicate that the previous transmission was in error. Then, you should continue the message starting from the last correctly spelled word. This allows you to correct the error and continue the message efficiently, without having to repeat the entire signal. The other options are incorrect because EEE is the signal to indicate an error in your own transmission (not the proper erase signal), repeating the entire signal (option D) is unnecessary after using the erase signal, and re-spelling the word (option B) is redundant once you've used the erase signal.
