Answer:
Object Y
Explanation:
Object W has 25N pushing to the left and 20N pushing to the right, so 5N pushing to the left. Object X has 10N pushing to the left with no resistance. Object Z has 25N on each sides, and the equal forces cancel each other out. Object Y has 80N pushing to the right with no resistance.
