Back testing VaR models involves comparing the predicted losses (VaR estimates) with the actual daily profits and losses to assess the accuracy and reliability of the VaR model. This process helps in validating whether the model is effective in predicting risk and in identifying any discrepancies between predicted and actual outcomes. Therefore, the correct statement about back testing the VaR models is option B.

The delta-normal method, which uses the delta to approximate the change in the price of an option, has limitations when dealing with options. This method can significantly misrepresent the risks associated with options, particularly because it only considers the linear component of the price change (delta) and ignores the convexity (gamma). Specifically, it tends to understate the risks of long positions in calls because it does not fully account for the increasing delta as the underlying asset price rises, leading to potential underestimation of the risk. Conversely, it overstates the risks of short positions in puts, as the delta of puts decreases less dramatically when the price of the underlying asset falls.

The Chief Risk Officer (CRO) should report to the CEO or the Board of Directors. This ensures that the CRO maintains independence from the business units whose activities they are monitoring and managing, which is critical for unbiased risk assessment and management.
