Which of the following is NOT a type of evidence?

Objection handling is a sales technique used to address and overcome a client's concerns or hesitations. While it's crucial for closing deals, it doesn't serve as independent evidence of an agency's capabilities or results. Testimonials are direct statements from satisfied clients, providing social proof of an agency's effectiveness. Awards are recognitions from industry bodies, signifying excellence and credibility. Case studies are detailed accounts of projects, showcasing problems solved, strategies implemented, and measurable results achieved. These three options directly demonstrate an agency's past performance and value, whereas objection handling is a skill applied during the sales process itself.
