The Correct Option is C

Solution and Explanation

The price elasticity of demand \(E_d\) is given by the formula: \[ E_d = \frac{% \text{Change in Quantity}}{% \text{Change in Price}}. \] Here, the price elasticity of demand is 4, and the desired percentage change in quantity is 10%. Let \( x \) represent the percentage change in price. Using the formula: \[ 4 = \frac{10}{x}, \] we find that \( x = 2.5 \). Thus, the firm must lower its price by 2.5% to achieve a 10% increase in sales. Final Answer: \boxed{2.5%}
