The correct answer is A) Clasp hands in front of your body. The hand signal to signal the crane operator to "dog everything" (secure the load) is to clasp the hands in front of the body. This is the standard hand signal recognized in the United States Coast Guard Captain's License Examination for instructing the crane operator to secure the load before lifting or lowering. The other options, while potentially hand signals, do not correspond to the specific "dog everything" signal as defined in the regulations and testing standards for Coast Guard licenses.
