Option A. The author uses anecdotal evidence to support the claim that solar energy helps the power grid.
Explanation:
The excerpt from "Catching Sun Rays" recounts the time on August 14th, 2003 where across the Northeast of the United States and Canada more than 55 million people were without power due to a massive blackout after a hot day. The author is using this story as support for the claim that solar energy is a better option that electric energy as it puts less pressure on power grids which would translate in fewer blackouts. The evidence is anecdotal as it is not based on research or data but rather is a recollection of a story that although fitting into the main theme of the story, it is not necessarily true or reliable to the topic it is supporting.
