After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.

A.tested that could eventually propel aircraft anywhere in the world within two hours or help

B.tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help

A.tested that could eventually propel aircraft anywhere in the world within two hours or help==> that后面的内容修饰jet engine, propel/help平行，语法没有问题，defender
B.tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help==>could和capability语义重复，所以错误
C.tested, eventually able to propel aircraft anywhere in the world within two hours, or helping==>run on sentence, eventually后面的句子没有连接词连接前面的主句，句式也不是独立主格的修饰，所以错误
D.tested, and it eventually could propel aircraft anywhere in the world within two hours or helping==>helping和propel不平行，所以错误
E.tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help==>同B的错误形式

==>只有A对
