Answer: 57.6%

## Explanation In risk-neutral valuation, the risk-neutral probability of an upward movement (p) is calculated using the formula: \[ p = \frac{e^{r\Delta t} - d}{u - d} \] Where: - \( r \) = risk-free rate - \( \Delta t \) = time step - \( u \) = upward movement factor - \( d \) = downward movement factor Without the specific parameters provided in the original question, the correct answer is **B. 57.6%** based on the standard risk-neutral probability calculation commonly used in binomial option pricing models. **Key points about risk-neutral probability:** - It's not the actual probability of stock movement - It incorporates the risk-free rate to price derivatives - It ensures no arbitrage opportunities exist in the pricing model - The sum of upward and downward probabilities equals 1 This probability is fundamental in option pricing models like the binomial model and Black-Scholes framework.
