The correct answer is "Support the head in the position you find it. Do not try to align it." This is because in a patient with a possible head, neck, or spinal injury, mobilization or moving the the head can potentiate more damage; especially to the cervical vertebra and cervical spine, producing dire consequences such as paralysis and paresthesias. The best thing to do is to support the head and attach a cervical collar, if possible.
I think the correct answer from the choices listed above is option C. Cnidarians is the name of lower Invertebrates that have a jelly-like layer between endoderm and ectoderm. Hope this answers the question. Have a nice day.
