Which sentence is punctuated correctly? new york is a vibrant, and very diverse city. new york is a vibrant, very, diverse city. new york is a vibrant, very diverse city.

New York is a vibrant, very diverse city.

Explanation:

In the first option, it is not right to use both a comma and "and" to connect a two-element list of modifiers ("vibrant" and "very diverse"). In the second option, a comma should not be isolating the adverb "very" from the adjective it modifies (diverse). Only the third option is properly punctuated.
