Step-by-step explanation:
The horizontal rows of a market-product grid signify d) Market segments. A market-product grid is a matrix that displays the relationship between a firm's markets (market segments) and its products. It helps businesses to visualize how different products can satisfy the needs of different market segments and to identify opportunities for market expansion or product development.
