hi

One study found that although government policy and the industrial sector in which a company operates can influence its productivity and financial strength, management decisions have at least as great an impact on a company’s performance.

A) management decisions have at least as great an impact
B) decisions by management have a great impact
C) manager decisions impact greatly
D) decisions by a company’s management impact greatly
E) what a company’s management decides has a greater impact

why b and e are wrong ??

Thanks
