Which of the following are characteristics of effective delivery in a speech?

Effective delivery in a speech is primarily characterized by articulation, vocal variety, and body language. Articulation refers to the clarity and precision with which words are pronounced, which is crucial for the audience's understanding. Vocal variety involves the modulation of pitch, tone, and volume, allowing the speaker to convey emotion and keep the audience engaged. Body language, including gestures, facial expressions, and posture, enhances the message and helps establish a connection with the audience.

These elements work together to create a dynamic and compelling presentation. When a speaker uses effective delivery techniques, they can emphasize key points and maintain audience interest, making the speech more memorable and impactful. In contrast, other options do not align with characteristics of effective delivery; for example, minimal eye contact and monotone voice can disengage the audience, while elaborate jargon and complex terminology can confuse rather than clarify the message.
