why not A?

The four perspectives used in the balanced scorecard are customer, internal process, workforce learning and growth, and financial. These perspectives provide a balanced view of the organization's performance by incorporating both financial and non-financial measures. The customer perspective focuses on how the organization is perceived by its customers and includes measures such as customer satisfaction and loyalty. The internal process perspective measures the efficiency and effectiveness of the organization's internal processes. The workforce learning and growth perspective focuses on the organization's efforts to develop its employees' skills and capabilities. The financial perspective measures the financial performance of the organization and includes measures such as revenue growth and profitability.
