B选项为何描述不正确

问题如下：

Which type of investor is likely to prefer investing in commodities using exchange-traded products?

选项：

A.Those seeking simplified trading through a brokerage account B.Those seeking to gain access to dynamic commodity trading strategies C.Those seeking expertise in a specific commodity sector

解释：

Exchange-traded products allow investors to gain commodity exposure through a simple exchange-traded instrument that can be accessed via a brokerage account. B is incorrect because it describes investors who choose to use commodity trading advisors.C is incorrect because this type of investor will choose a specialized commodity fund for its expertise.ETP是允许投资者通过经纪账户来获得大宗商品敞口，因此A是正确的。B选项是CTA的特征，C是Specialized funds。
