The correct answer is strategic prospecting, planning and needs analysis, strategy and solutions, presentation and close. This answer accurately describes the stages of the sales funnel. Strategic prospecting involves identifying potential customers, planning and needs analysis involves understanding their needs, strategy and solutions involves developing a sales strategy, presentation involves presenting the product or service, and close involves finalizing the sale. The other option, cold calling, ad schedules, processing ads and credits, does not accurately describe the stages of the sales funnel.
