I might be wrong, but I think the error is the way they spelled okay. When you are writing in an essay or any other forms of writing, I think you’re supposed to spell the word out instead of abbreviating it.
I hope this helps :)
The answer is B) They are always focused on a main idea.
Paragraphs are not always indented; it depends on the writing format. They vary in length from short to long. They do not always have a topic sentence; some writers organize their thoughts and paragraphs well without topic sentences.
Hope this helps! :)
