B正确。里森应当采用低风险、收益率有限的套利策略，但是他却在日本股指期货和利率期货、期权上进行了巨额的投机。当里森欺诈外界，捏造自己的投资业绩时，管理层没有调查里森的高额利润的来源。

----------------------------------------------------------------------------------------------------------------------------------

B is correct. Leeson was supposed to be running a low-risk, limited return arbitrage business out of his Singapore office, but in actuality he was investing in large speculative positions in Japanese stocks and interest rate futures and options. When Leeson fraudulently declared very substantial reported profits on his positions, management did not investigate the stream of large profits even though it was supposed to be associated with a low-risk strategy.

A, C, and D are incorrect.
