Yes. The punctuation is correct and it is a complete sentence. Nice job!
The purpose of drawing conclusions is to READ FOR MEANING.
Reading for meaning involves understanding both the written and the implied information in a particular story. There is no way one can possibly draw correct conclusions if one doesn't understand what has been read.
Conclusions are drawn by using clues from the passage read to develop a reasonable judgement.

Elimination is always the best. Pick out the worst possible answers, so it'll give you less choices to pick from. Or you could always pick c. I wouldn't advise that. Good luck on your test. :)
