To determine which marketing philosophy focuses mainly on the existing product, let’s analyze each concept:

1. Selling Concept:

   • Focuses on aggressive sales techniques and persuading customers to buy products, even if they are not needed.
   • It does not focus primarily on existing products but rather on pushing sales.

2. Production Concept:

3. Product Concept:

   • Focuses on the product itself, including quality, features, and innovation.
   • The belief is that customers will prefer products that offer the best quality and performance.
