Final answer:
Firms attempt growth through unrelated diversification primarily for risk reduction and resource utilization. Strategic fit is not typically a motivating factor for unrelated diversification since the industries may not have complementary aspects.
Step-by-step explanation:
Firms may attempt growth through unrelated diversification for several reasons, but the option that does not typically motivate unrelated diversification is strategic fit. Unrelated diversification primarily involves a firm expanding into industries that are not related to its current business. The benefits of this strategy often include risk reduction, as it allows a company to spread its risk across different industries. It also may improve resource utilization, making use of excess capital or managerial capabilities. However, unlike related diversification where synergy and strategic fit are major considerations, these do not typically drive unrelated diversification since the businesses are in different areas and may not have complementary aspects.
