because of和due to有什么区别？

Q22:

On account of a law passed in 1993, making it a crime punishable by imprisonment that a United States citizen hold gold in the form of bullion or coins, immigrants found that on arrival in the United States they had to surrender all of the gold they had brought with them.

1. On account of a law passed in 1993, making it a crime punishable by imprisonment that a United States citizen hold
2. With a law passed in 1933 that makes it a crime punishable by imprisonment that a United States citizen hold
3. A law passed in 1933 that made it a crime punishable by imprisonment for a United States citizen holding
4. Because of a law passed in 1933 making it a crime punishable by imprisonment for a United States citizen to hold
5. Due to a law being passed in 1933 that makes it a crime punishable by imprisonment for a United States citizen to hold

E选项除了那个being比较碍眼之外，due to能不能用呢？请赐教

due to没问题.

问题出在being和定语从句.that不是跟1933而是跟law.

但是我翻了一个老贴上面是这样写的：

看到很多人对due to和because of的区别都不太清楚，做题的时候不能根据这两个词本身排除，还要找别的因素。其实这两个词是有很大区别的，我是看到了一个鬼佬的解释才彻底明白：

Due to means"cause by". It shoud only be used if it can be substitued with "caused by".

It doed not mean the same thing as "because of ",

Incorrect: The game was postponed due to rain.

Correct: The game was postponed because of rain.

Correct: The game's postponement was due to rain.

以后再遇到due to只要把它换成我们熟悉的caused by就清楚多了。

请问本题的正确答案是什么？
