Explanation:

Words of the same syntactic function are separated by commas if they do not come together by e, or and neither. And this was done correctly in letter A.

These words can be subject, predicate, adjunct adverbial and adnominal, noun, vocative, bet, etc. In the case of the phrase shown in letter A, the use of the comma was used correctly to separate the nouns "newspapers", "news magazines", "radio" and "television".
