First of all you should give more points for someone to write a paragraph or 2 for you but… I will not type it for you but first Read the original theme because I don’t know the theme.. but I did something like this last year. Basically for example a peanut butter and jelly sandwich. You’d put it in a order. First you must open up the fridge, then take out the peanut butter and jelly, then get your bread, open the bread and take out 2 slices, open the peanut butter and jelly, open a drawer and get a knife or two, take the knife and scoop peanut butter on it and spread it on a piece of bread, then wipe your knife or use the other knife and scoop jelly on it and spread it on the bread, then put both pieces of bread together and enjoy eating it.
Well, because the word 'mother' is the English translation of the Latin word 'mater', they mean the same thing. So, I am assuming we are supposed to find two words which have the same etymology like this one, to complete the analogy. So, I believe the answer is A) autonomy : autos, because 'autos' is the root of the word 'autonomy', the same way 'mater' is for 'mother'.
