GWD13-11 请教

Q11:

A South American bird that forages for winged termites and other small insects while swinging upside down form the foliage of tall trees, the graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are represented in virtually every kind of habitat.

1. graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are
   
2. graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and  is
   
3. graveteiro belongs to the ovenbird family, a group of New World tropical birds that include more than 230 species and  is
   
4. graveteiro, which belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are
   
5. graveteiro, which belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and is

答案是B, 我人为是A.a group of New World 是the ovenbird family的同为语, and连接两个that定语从句修饰birds.而B 选项 is做a group 的谓语,变成句子, 与前 belongs to 并列,但缺连词.

恳请指正!
