Concept:Vertical integration is the combination of different successive stages of production and distribution in the same industry under one owner or management.
Explanation:Musa’s sheep supply the raw material, wool.
The raw wool is then spun and transformed into cloth, which is the processing stage.
Afterwards, the finished cloth is sold directly to final consumers, representing the distribution stage.
Therefore, Musa covers raw material acquisition, manufacturing, and marketing within a single production chain.
Horizontal integration would involve combining firms at the same production stage, so this option does not apply.
Since Musa’s activities span more than one successive stage in the textile industry, the arrangement is best described as vertical integration.
Answer:A. Vertical integration.
