Which of the following can be in logical arguments?

The correct answer is A. Imperative statements.

Explanation: In logical arguments, we typically use declarative sentences that state facts or beliefs. Imperative statements, which give commands or requests, can also be part of logical reasoning in specific contexts, especially when discussing obligations or actions. Normative statements express values or judgments and are not strictly logical arguments. Questions and fragments do not contribute to forming logical arguments effectively.
