I would say perhaps 'instructions on how to do something'. This would be more beneficial to some with the use of a visual aid, and by this, it would truly help the. In this case, it would be a 'dvd' player, and also cables that this person may be needing help with, and by this, the kind of aid that they would be able to use would be something like instructions, by them reviewing this, they would be able to recap if they would want to come back to it, and also, they would most likely be able to meditate, and understand how to put 'plug a' and 'plug b' together and also do this in the future as this will help them. Your answer would this be (option C).
