Question

to select the best strategy available to them, marketers should consider
○ when they want promotional messages delivered to customers.
○ how to get their product into more customers’ hands.
○ how the marketing concept applies to their situation.
○ resources needed to research and develop their product.

Explanation:

When selecting the best marketing strategy, understanding how the marketing concept (focus on customer needs, value, etc.) applies to their specific situation is fundamental. The other options are more tactical (delivery of promo messages, distribution, R&D resources) rather than the core strategic consideration of aligning with marketing concepts.

Answer:

how the marketing concept applies to their situation.
