A salesman who achieves high commissions is showcasing proficiency in which area?

The correct choice is technical skills. A salesman who achieves high commissions typically demonstrates an in-depth understanding of the products or services they offer, which is a component of technical skills. Technical skills refer to the knowledge and abilities related to specific tasks or areas of expertise. In sales, this could include a strong grasp of product features, an understanding of the market, and the ability to analyze customer needs effectively.

Successful salespeople must also possess the ability to apply their technical knowledge in conversations with clients, demonstrating how a product meets their specific requirements. Their ability to explain complex technical details in a way that is understandable to customers is critical for closing sales and generating commissions.

While interpersonal skills, managerial skills, and negotiation skills are important in the field of sales, they are not the primary reason a salesman achieves high commissions. Interpersonal skills facilitate building relationships with customers, and negotiation skills help in finalizing deals, but these skills often rely on a solid foundation of technical knowledge to be effective.
