To determine which sentence has no punctuation, spelling, or grammar mistakes, we can analyze each option and identify any errors.

A) Las Vegas, a city that was built on gambling, is somehow getting by in this economy.
This sentence appears to be grammatically correct and properly punctuated.

B) Las Vegas: a city which was built on gambling, is somehow getting by in this economy.
In this sentence, the use of a colon after "Las Vegas" is incorrect. A comma would be more appropriate.

C) Las Vegas, a city, which was built on gambling is somehow getting by in this economy.
This sentence is missing a comma after "city." Additionally, it would be more grammatically correct to use "that" instead of "which" to introduce the defining relative clause.

D) Las Vegas; a city that was build on gambling is somehow getting by in this economy.
This sentence contains two errors. Firstly, the semicolon after "Las Vegas" is incorrect, and a comma should be used instead. Secondly, the word "build" should be "built" to maintain proper verb tense.

Based on these analyses, the sentence with no punctuation, spelling, or grammar mistakes is:
A) Las Vegas, a city that was built on gambling, is somehow getting by in this economy.
