Final answer:
The word that correctly completes the sentence 'He envisioned a day of zero ___' is 'exertion' (Option B), which means effort or physical work, and represents what Deacon is looking to avoid on his day off.
Step-by-step explanation:
Deacon wanted to have a lazy Saturday to himself. All week, he completed schoolwork, helped at his family’s store, and practiced for hours with his band. He felt like he was always on the move with no time to himself. He envisioned a day of zero exertion, just lounging around, no phone calls, no errands, just peace. Then his friend invited him to meet at the park for a game of hoops. Maybe next Saturday….
The correct word to complete the sentence would be 'exertion' (Option B). In the context of the sentence and Deacon's desire for a relaxing day, 'exertion' means effort or physical work, something Deacon hopes to avoid on his desired day off.
