its obviously a

think about it...BATTERY powered

that means it starts with chemical because batteries use acids...that narrows it down to a and b

then what does the battery power? it doesnt power the hands directly...it powers an electrical device which powers the hands...(hands being mechanical)

therefore the only logical answer is A

hope i helped /tongue.gif\' class=\'bbc_emoticon\' alt=\':P\' />

mechanical isnt a form of energy, it would have to be kenetic or potential. hope this helped
