Choose the answer which best rewords the italicized portion. If you think the original wording is best, choose option A.
“The California Right to Know Genetically Modified Food Act” known as Proposition 37 will require food manufacturers to label food with genetically modified ingredients (GMOs).
Explanation
Answer: B - The best choice is “Act,” known as Proposition 37 will,”
The expression “known as Proposition 37” includes relevant information, but is not needed to complete the sentence. Therefore, it is a parenthetical expression and should be offset by commas at the beginning and at the end of the phrase. Generally, commas are inserted before quotation marks. The comma should appear after “Act” and before the quotation marks.
