which choice completes the text so that it conforms to the conventions of standard english?
choose 1 answer:
a stanford;
b stanford,
c stanford
d stanford:

Explanation:

Commas are used to separate items in a list. Here, "Barry Sharpless", "Carolyn Bertozzi", and "Morten Meldal" are presented as a list of Nobel laureates. The part about Carolyn Bertozzi (founder of The Bertozzi Group at Stanford) is an additional description within the overall list structure. A comma is needed after "Stanford" to separate this description from the continuation of the sentence (mentioning Morten Meldal). A semicolon (;) is for stronger separation (like between independent clauses in some cases, not for this simple list - like description). A colon (:) is for introducing something (like a list after a complete sentence, but here it's not the case). Omitting punctuation (option C) would make the sentence structure incorrect as it wouldn't properly separate the description about Carolyn Bertozzi from the rest.

Answer:

B. Stanford,
