OG-11TH-122 like 的用法有点怪

122. More than 30 years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to
            another.

(A) as pearls moving mysteriously from one necklace to another

B        Correct. In this sentence, the preposition like properly introduces the phrase.

C       McClintock^'s simile creates an image that is not real; the use of the verb
                            do indicates the pearls' movement as a reality

D       Like incorrectly introduces a clause; the verb do indicates a reality instead of an image that is only imagined

E        Pearls do not actually move; McClintock is suggesting an image only. Some other one is a wordy replacement for another

请问选项B里的like 用法，like 后面跟的究竟是什么结构啊，独立主格结构还是，VING修饰LIKE充当名词功能？OG-11TH-126明确指出like 后面跟的短语不能有主语和谓语

Clauses have subjects and verbs and are introduced by conjunctions or relative pronouns; phrases do not have subjects and verbs and are frequently introduced by prepositions. The preposition like, not the conjunction as, should introduce the underlined phrase.

A       As incorrectly introduces a phrase when like is required

B        Correct. In this sentence, the preposition like properly introduces the phrase.

C       McClintock^'s simile creates an image that is not real; the use of the verb
                    do indicates the pearls' movement as a reality

D       Like incorrectly introduces a clause; the verb do indicates a reality instead of an image that is only imagined

E        Pearls do not actually move; McClintock is suggesting an image only. Some other one is a wordy replacement for another

请问选项B里的like 用法，like 后面跟的究竟是什么结构啊，独立主格结构还是，VING修饰LIKE充当名词功能？OG-11TH-126明确指出like 后面跟的短语不能有主语和谓语

as 后跟句子，

like 后跟名词,

窃以为in option (B),"moving mysteriously from one necklace to another"是-ing分词修饰名词pearls.  所以并没有出现所谓的谓语.

一点拙见
