The majority of your presentation's impact comes from vocal, facial, and postural presentation. This is because these aspects of communication can greatly affect how your message is perceived and received by your audience. Option A (10%) is not a high enough percentage to account for the significant impact of vocal, facial, and postural presentation. Option B (50%) is closer to the correct answer, but still underestimates the impact of these elements. Option D (7%) is a low percentage and does not reflect the significant role that vocal, facial, and postural presentation play in effective communication. Therefore, option C (93%) is the most accurate choice.
