You just have to combine like terms. Hope it helps.

Well, let's see... I don't know what a coordinating conjunction is off the top of my head, but I know B isn't the answer, since 'independent' means 'highly capable of handling oneself'. C <em>certainly</em> isn't the answer, simply because you can see by this answer they obviously do combine with a dependent clause from time to time. That leaves us with D and A, which both leave the same term. However, I do believe I can use the word preceding <em>conjunction</em>, which is <em>coordinating</em>, to realize that 'and,' 'but,' and 'or' are coordinating conjunctions. Seriously, D cannot be the answer because not every sentence starts with any of those. So your answer is A.
Thinking about Grendel, I think 'A' is most likely.
This happens quite a lot in verbs e.g run to running. It is because you double the last consonant in a one-syllable noun for it to become a verb. (Keep in mind there are exceptions to this rule.)
