[单选,材料题] What was Ponzi’s crime?

回答下面的题目：
From Ponzi to Madoff
The year was 1920．The country was the United States of America．The man’s name was Charles Ponzi．Ponzi told people to stop depositing money in a savings account．Instead，they should give it to him to save for them．Ponzi promised to pay them more than the bank．For example，a savings account might pay you$5 a year for every$1 00 you deposit．Ponzi，however，would pay you $40 a year for every $1 00 you gave him to hold．Many people thought this was a good plan．They began to give their money to Ponzi．
How could Ponzi make so much money for people? This is what he did with the money people gave him：He used some of that money to pay other people who gave him money．However，he also kept a lot of the money for himself．Soon he had $250 million．This was a kind of theft，and it was against the law．The people who gave him their money didn’t think anything was wrong．Ponzi paid them every month，just like a bank．Ponzi continued this way of working for two years．Then one day，
he didn’t have enough money to pay all the people．They discovered his crime，and he went to prison for froud．
Ninety years later，people began to hear about a businessman in New York named Bernard Mad off．People said he gave good advice about money．They said when they gave him their money，he paid them a lot more than the bank．Mad off helped hospitals，schools，and individuals earn money．Over a period of 40 years，people gave him$1 70 billion．However，no one investigated what he did with the
money．The people who gave Mad off their money also didn’t think anything was wrong because he paid them every month．
One day，Mad off didn’t have enough money to pay all the people he needed to pay．That’s when people discovered how Madoff worked：He was taking money from some people to pay other people， just the way Charles Ponzi did．However，this time，instead of losing millions of dollars，people lost billions．
Madoff was accused of fraud，and United States government officials arrested him．He didn’t have to go on trial because he said he was guilty．In 2009，a judge sentenced him to 150 years in prison．Bernard Madoff’s crime was even bigger than Ponzi’s．It was the biggest fraud in history．The lesson of this story is clear：When something seems too good to be true，it probably is !

A . He kept a lot of other peoples’money for himself__________．
B . He robbed the banks of millions of dollars．
C . He gave people more than bank allowed．
D . He didn’t pay people the interests．
