The correct answer is: A) emotional or passionate statements.
Remember that logos stands for "logic" from ancient Greece, that means it appeals to reason or logic. In literature it is a device characterized as a statement, sentence or argument used to convince or persuade the audience that uses both reason and logic, meaning it has to be based on evidence and facts. In this case the orderly presentation of facts and definite arguments makes our statements logical by following a clear line of thought; showing facts or statistics helps us support our statements giving strong evidence.
Emotional statements belong to a different literary device named <em>phatos</em> related to the emotional appeal.
Well, there are three types. Logos, pathos and ethos. Since a.(emotional or passionate statements) is mostly connected to pathos which makes a deep connection with the audience or reader, I'd say (a.) is the answer.
