interesting question… I never thought about this as a Chinese. All on the right side are correct. You can't say, 水果放在桌子上. Because there are no legs on 水果. 水果 must be put on the table by someone. When you say,把水果放在桌子上, which means (你/我/他) 把水果放在桌子上。汽车和包裹的句子也是一样的。

*don't suppose school... sorry., a mistake

usually…we'd just say 地上怎么乱七八糟的 or if you want to empathize lots of stuff on the floor, you could say 地上怎么这么多东西，乱七八糟的。
