I'm almost sure that the answer is B, when you are writing an analytical essay about any topic -or any essay for that matter- you must have a main argument that can be supported -this is why you have to have 3 body paragraphs, each give a reason or support the claim (argument)-
Im Indian and this makes no sense sorry :(
Even though you didn't underline anything, there is only one pronoun in this sentence - the word them.
The case of this pronoun is objective - it functions as an object in the sentence. It is really easy to determine this - all you have to do is ask the questions <em>whom </em>or <em>what. Whom did the designer dress in black and teal costumes? </em>And the answer is - <em>Them. </em>
This way you know that the pronoun is also the object; to be more specific, it is a direct object.
Therefore, the correct answers are case: objective; function: direct object.
It is simple first you choose your topic and then you can either have it ryme or not.
