d. helen feels water on her hands and makes a connection between objects and language.

The correct answer to this is:

D.Helen feels water on her hands and makes a connection between objects and language.

In this chapter, Helen Keller describes her first experiences with her new teacher.  Keller finally understood the idea that a word Anne Sullivan, her new teacher, is spelling “water” corresponds to the water flowing over Keller’s hand.  This realization led Keller to create connections and open doors of knowledge and opportunity previously closed to her.
