Answer: Growth in market share

### Explanation Forecasting a company's revenue typically involves either **top-down** or **bottom-up** approaches. - **Option A (Net interest income)**: This is a **bottom-up** driver, as it is calculated based on account balances and revenue yields (e.g., loans multiplied by interest rates minus deposits multiplied by their interest rates). - **Option B (Growth in market share)**: This is a **top-down** driver. Analysts first forecast the growth rate of the company's product market and then assess the company's current and projected market share. - **Option C (Growth in the number of branches)**: This is also a **bottom-up** driver, as it is a capacity-based measure (e.g., retail stores or bank branches and their sales per unit). Thus, **Option B** is the correct answer as it aligns with the top-down forecasting approach.
