Answer:
The sentence that is punctuated correctly is One play that I would like to read is Julius Caesar.
Explanation:
The sentence One play that I would like to read is Julius Caesar includes a subordinate clause -that I would like to read- introduced by the restrictive pronoun that. This pronoun defines, restricts or limits the thing it is referring to (in this case, play) so the clause is essential to the meaning of the sentence. Since no commas should be used to set off the restrictive element in a sentence, One play that I would like to read is Julius Caesar is punctuated correctly.
