Vasicek Interest Rate Model Characteristics

In the context of the term structure of interest rates, various models are used to explain and predict interest rate movements over time. One of the most widely recognized models is the Vasicek model, which employs a specific approach to interest rate dynamics.

The Vasicek model assumes that interest rates follow a mean-reverting process, and it includes parameters such as the long-term mean rate, the speed of reversion, and the volatility of interest rates. Understanding the implications of these parameters is crucial for managing fixed income portfolios and for pricing interest rate derivatives.

Given this context, which of the following statements correctly describes a feature of the Vasicek interest rate model?
