AI Explanation
The correct answer is A) raise the boom and lower the load. The signal of the signalman with his arm extended, thumb pointing up, and fingers flexing in and out indicates that the crane operator should raise the boom and lower the load. This is a standard hand signal used in crane operations, as outlined in the OSHA regulations on crane signaling. The other options are incorrect because they do not match the specific hand signal being described.
