A) Editorials are published regularly in newspapers both in print or online.
Let's just look at process of elimination. Option A is a true statement. Editorials are published regularly in newspapers in print and online. Option B is not necessarily true as the editorial staff doesn't always write them. They do choose what is published however. Option C is also not necessarily true. Editorials in highly respected newspapers are usually more direct and concise than editorials in a small local newspaper. Option D editorials are also not necessarily less dramatic. Since option A is the only one that is consistently true, it is the best answer.
