Answer:
B. Loretta has a collection of old vinyl records that she keeps in her moldy, dusty attic.
Step-by-step explanation:
Punctuation is the correct use of grammatical signs/ marks so that the sentence can be deemed correct and have a meaning. It involves various marks such as the comma, colon, semi-colon, question marks, full-stop, etc.
From the given options, the sentence that best uses the correct punctuation signs is the third sentence. In sentence B, the use of the comma is correct while the other sentences have mistakes about how or where the commas/ pauses are placed.
In sentence B, the words "moldy, dusty" are adjectives that modify the noun "attic", therefore the need to separate them by a comma.
Thus, the correct answer is option B.
