Dramatic monologue

In drama, a speech given entirely by one person or character is called a dramatic monologue.

The speech given entirely by one person or character in drama is called a dramatic monologue.

To arrive at this answer, we can break down the choices and deduce the correct option:

1. Closed communication: This term generally refers to a form of communication in which information is only shared between a limited number of individuals or within a specific group. It does not specifically relate to speech in drama.

2. Dialogue: Dialogue is a conversation or exchange of speech between two or more people or characters. Since the question specifies that the speech is given entirely by one person or character, dialogue does not fit.

3. Conversation: Similar to dialogue, a conversation refers to an exchange of speech between two or more individuals. Therefore, it does not match the condition of the question.

4. Dramatic monologue: This term refers to a poetic form in which a character speaks directly to an audience or an imaginary listener. The important keyword here is "monologue," which indicates a solo speech. Therefore, dramatic monologue is the correct answer in this context.
