Answer:
d. A market-coverage strategy in which a firm decides to ignore market segment differences and go after the whole market with one offer
Explanation:
In an undifferentiated market, the market is not divided into segments and rather the whole market is taken up employing the same marketing mix of similar products available for similar prices in similar places or markets and employing similar promotion activities.
Such a marketing strategy would be suitable in markets where consumers have similar needs and requirements for a particular product. For example this strategy maybe used for marketing of soft drinks.
Here, the whole market represents one homogeneous group to the marketer.
