Answer:
B. She learned that she could overcome obstacles.
Step-by-step explanation:
"The Story of My Life" by Helen Keller is a memoir where the blind and deaf author talks about her childhood and how she came to overcome her physical disabilities. The book provides an inspiring insight into the struggle of Keller and how she came to embrace life without the necessary sight and sound.
In the given excerpt, Keller recollects how she first learned about water and how she was helped by her teacher Miss Annie Sullivan to 'spell' water. This experience not only taught her how to spell and 'understand' water but also gave her a whole window of realization. It was at this moment that she knew and realized the potential she has, the barriers she can overcome, and enjoy life like other people, even though through a much different aspect.
Thus, the correct answer is that she learned she could overcome the obstacles in her life.
