The correct sentence is: Each of them brings an ingredient: noodles, mushrooms, or pasta sauce.
Explanation:
1. In this sentence, the subject is "Each," which is singular, so the verb should also be singular to match it.
2. The verb "brings" is the correct form for the singular subject "Each."
3. The sentence is structured properly with a colon to introduce the list of ingredients.
4. The options "Each of them bring an ingredient," "Each of them bring an ingredient, noodles, mushrooms, or pasta sauce," and "Each of them bring an ingredient; noodles, mushrooms, or pasta sauce" are incorrect because they use the plural form of the verb "bring," which does not agree with the singular subject "Each."
Therefore, the correct sentence is: Each of them brings an ingredient: noodles, mushrooms, or pasta sauce.
