B. First risk budgeting, then risk exposure, last risk tolerance.
C. First risk exposure, then risk tolerance, last risk budgeting.
解释：
A is correct.
Risk tolerance is the first step in which one enterprise should identify and measure the risk and define the risk appetite. Based on the results of risk tolerance, risk budgeting can proceed to determine which and how much risk is taken. Lastly, risk exposure can be measured and compared with an acceptable risk.
