Final answer:
The shortage of potassium iodide can be attributed to high demand, but without specific information, we cannot ignore potential production issues which could also contribute to the shortage.
Step-by-step explanation:
When analyzing a shortage of a product, such as potassium iodide, there could be several contributing factors. Answering a question on whether a shortage was caused by high demand requires an understanding of supply and demand dynamics. In this case, if we select option A, we’re indicating that the high demand for potassium iodide was the sole reason for the shortage. However, option C suggests that high demand, in addition to production issues, caused the shortage. Without specific details regarding the situation, it's hard to determine the exact cause, but typically a shortage is due to a combination of high demand and supply constraints.
