Final answer:
Reducing the volatility of demand is a reason for marketing industrial goods abroad that doesn't necessarily apply to consumer goods because the latter typically has more stable demand patterns.
Step-by-step explanation:
Among the options provided, the reason for marketing industrial goods abroad that does NOT necessarily apply to consumer goods is c) reducing the volatility of demand. Industrial goods markets can often be subject to fluctuations due to business cycles, technological advancements, and changes in business needs.
By expanding to international markets, companies can stabilize their demand by tapping into different markets and business cycles, which could compensate for slowdowns in domestic demand. This approach of diversifying markets helps manufacturers of industrial goods to smooth out the fluctuations and plan their production and inventory more effectively.
Consumer goods, on the other hand, are generally aimed at a broad audience and their demand is usually more stable and less influenced by the factors affecting industrial goods. This stability arises from the continuous need for consumer products that serve everyday purposes, which makes consumer markets less susceptible to sudden changes in demand.
