C， see sb. do sth 和see sb. doing sth 两种表达，see sb. do sth表示看到动作全过程，比如，我看到他进了书店I saw him go into the bookstore. see sb. doing sth 表示当时看到某人正在进行的动作，比如，那时我恰好看到他在跑步I happened to see him running at that time.明显选项只有C才是see sb. doing sth 。如果是see sb.（being） done sth,则为看到某人（正在）被怎样， 比如被狗咬了I saw him bitten by the dog.而see sth done就是看到某事被做了。
如果你是小学或初中生只要记see sb. do sth 和see sb. doing sth 两种表达，高中就要记住see sth done了。
on the way home 是因为home是副词， 要省略to.如果是school shop就要on the way to school/shop
事实上 see sb. do sth 是省略to的不定式，当改为被动时要还原to,
I saw him go into the bookstore= He was seen to go into the bookstore by me.
I saw him running at that time=He was seen to be running by me.
我拓展了很多，你能记住多少记多少

我选B，呵
