The correct answer is A. Ideas follow a logical order and connect to each other clearly
Step-by-step explanation:
In writing, the word "coherence" refers to the connection between clauses, sentences, and ideas in a text in which all elements are organized in a logical way, connected between each other and these developed effectively the main idea of a text. This implies coherence mainly refers to the logical organization and connection between the elements or units of a text and therefore, if you are editing a composition and you want to focus on coherence you should mainly check all ideas follow a logical order and connect to each other clearly rather than checking grammar, sentence length or the order of paragraphs, because coherence does not deal with these elements but with the logical connection between elements in a text and the way these developed the main idea.
