Heirloom tomatoes, grown from seeds saved from the previous year, only look less appetizing than their round and red supermarket cousins, often green and striped, or have plenty of bumps and bruises, but are more flavorful.

A. cousins, often green and striped, or have plenty of bumps and bruises, but are

B. cousins, often green and striped, or with plenty of bumps and bruises, although

C. cousins, often green and striped, or they have plenty of bumps and bruises, although they are

D. cousins; they are often green and striped, or with plenty of bumps and bruises, although

E cousins; they are often green and striped, or have plenty of bumps and bruises, but they are

答案是E, 可我认为E中的they指代不明确，可能指代cousins, 但需要指代Heirloom tomatoes.从转折的意思来看，后面应该用but, 而不是although, 所以我的答案是A.但我也不确定。

如果选A,often green and striped就变成修饰cousins了，本来是应该是修饰heirloom tomatoes的。

E里面，有分号隔开，they 就是指主语heirloom tomatoes。
