Answer:
C, it’s because you are describing something possessive.
B, Plot summary. My reasoning is because this will summarize the plot happening in this sentence.

The answer is C: Moving through the darkness.
The fact the question is asking about the adventures of a guide dog or the blind entails that it probably is a form of narrative, fiction or otherwise, which means it must be written to appeal to a reader´s fancy. So the title you should be looking for in the answer is one that is enticing or captivating at first glance, in a narrative sense. Also, semantically, and considering the reason stated previously, answer C is the only one that is interpretatively connected to a guide dog or the blind narratively.
The benefits of having more than one narrator include having more opinions and more than on side of a story.
