The main objective of communication is

The main objective of communication is to convey messages effectively. This often involves sharing facts, ideas, or instructions, and influencing the recipient's thoughts or actions.

Let's evaluate the options:

• A. Skill and personality development. While communication can aid in these areas, they are generally considered outcomes or benefits, not the primary objective itself.
• B. Need. This is too broad and vague. Communication fulfills needs, but "need" is not the objective.
• C. Information and persuasion. These are two fundamental and widely recognized objectives of communication. Communication is used to inform others and to persuade them to adopt a certain viewpoint or take action.
• D. Control and management. These can be objectives in specific contexts, such as organizational communication, but they are not as universally encompassing as informing and persuading for all forms of communication.

Therefore, the most accurate and comprehensive answer among the choices for the main objective of communication is information and persuasion.

The correct option is:

• C. Information and persuasion.
