Answer: Yes

**Explanation:** Spreadsheet models are highly appropriate for sensitivity analysis in equity valuation for several reasons: 1. **Flexibility**: Spreadsheets allow analysts to easily modify assumptions (like dividend growth rates) and immediately see the impact on stock valuation. 2. **Scenario Analysis**: Analysts can create multiple scenarios with different dividend growth patterns to test how sensitive the stock's value is to these assumptions. 3. **Efficiency**: Spreadsheets automate complex calculations, making it practical to test numerous assumptions quickly. 4. **Real-world Application**: In practice, dividend growth patterns are rarely perfectly stable, and analysts frequently use spreadsheet models to test various growth scenarios. Option B is incorrect because dividend patterns don't have to be stable - analysts often model changing growth rates. Option C is incorrect because spreadsheets are excellent tools for sensitivity analysis.
