真心请教OG12-66

66.  The 32 species that make up the dolphin family are closely related to whales and in fact include the animal known as the killer whale, which can grow to be 30 feet long and is famous for its aggressive hunting pods.
(A)    include the animal known as the killer whale, which can grow to be 30 feet long and is
(B)    include the animal known as the killer whale, growing as big as 30 feet long and
(C)    include the animal known as the killer whale, growing up to 30 feet long and being
(D)    includes the animal known as the killer whale, which can grow as big as 30 feet long and is
(E)    includes the animal known as the killer whale, which can grow to be 30 feet long and it is

答案是A，这个没有问题，但是问题在于OG解释C：
C    The participial growing might refer to the 32 species; the introduction of being is unnecessarily wordy and adds nothing in terms of meaning.  为什么说being在这里是多余的呢，不是固定短语be famous for吗，想了好久都想不通啊，苦恼ing。。。。

顺便跪问楼上nn，按照解释的说法，这句是不是就对了：
The 32 species that make up the dolphin family are closely related to whales and in fact include the animal known as the killer whale, (an animal) famous for its aggressive hunting pods.
我在想独立主格。
如果不加an animal这句有没有歧义乜？
