Answer:
d. divides a market into distinct groups that will respond similarly to marketing actions.
Step-by-step explanation:
Market segmentation refers to dividing a large market into segments or group of potential customers that share similar characteristics between them, e.g. a demographic segmentation focuses on ethnic groups, socio-economic status, education, gender, etc.
This way the company can focus similar marketing actions towards each segment, e.g. show ads in Spanish for Latin communities, focus on luxury products for wealthy segments, etc.
