The items that are considered marketing input data from the options provided are:
- Marketing budget reports
- Salespeople's call reports
- Advertising expenditures
These items relate directly to marketing efforts and data that contribute to decision-making and strategies in marketing.
While "accounting records on shipments" may support sales and inventory aspects, and "social media posts from consumers" may provide insights into consumer feedback (more of an external factor), they are not classified as direct marketing input data.
