A car manufacturer designs one marketing campaign for young, budget-conscious first-time buyers and an entirely different campaign for affluent, luxury-focused buyers. This is an application of:

Correct Answer: B) Segmentation and differentiated targeting based on distinct customer group needs and preferences — the manufacturer identifies two distinct customer groups and tailors a separate campaign to each one's needs — precisely what segmentation and differentiated targeting involve. Why the other options are excluded: • A (product diversification) refers to adding new products to a portfolio — the scenario describes tailoring communication to existing distinct customer groups, not launching new products. • C and D each describe a specific STP mistake — but this scenario describes a deliberate, well-reasoned segmentation strategy, not an error. Example (Pension Sector): PFRDA's distinct outreach strategy for unorganised-sector workers (via APY) versus government/corporate employees (via NPS) is a similar application of segmentation and differentiated targeting.
