The correct answer is C. An increase in its customers' disposable income
Explanation:
In businesses, the SWOT analysis helps a business grow and improve by considering its strengths which refer to advantages or qualities; weaknesses or areas to improve; opportunities or factors that can contribute positively; and threats or factors that might influence negatively.
In this context, external opportunities refer to factors beyond the control of the business that can make it grow. This includes an increase in the customers' disposable income, which refers to the money customers can spend as they wish because if customers have more money to spend the sales of the business can increase.
