Answer:
A. The author's infatuation with girl.
Step-by-step explanation:
In this excerpt from a short story Araby by James Joyce we are introduced with a young boy who fell in love with a girl who lives across the street. He waits in the front room of his house for her to appear and then hastily runs outside to follow her until their paths split. Expressions like when she came out on the doorstep my heart leaped, then her name was like a summons to all my foolish blood and the fact that he waits for her every day give us a clear statement of author`s infatuation with the girl.
