The correct answer is B. audience and purpose.
When it comes to her speech Address to the Troops at Tilbury, she obviously wanted to encourage her soldiers to be strong and unwavering.

An appositive is a noun/pronoun phrase that re-classifies/names the noun beside it.
Example, the dog, Ginger, barked happily at me.
The appositive would be Ginger. 'Ginger' renames/names ''the dog''.
The noun is Hemingway's novel, what renames it is 'The Old Man and the Sea'.
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'.
