问题如下：
We can use VAR to design better investment guidelines because :
I. VAR limits are comparable across assets.
II. VAR can supplement notional limits
选项：
A. I only.
B. II only
C. Both I and II.
D. Neither I nor II.
解释：
C is correct.
考点：Monitoring Risk With VAR
解析：statement I正确，VAR limits 在不同的资产类别之间具有可比性。statement II正确，只考虑对头寸的限制是不足的，头寸限制过于简单且可能无效，VAR可以补充notional limits的不足。
什么是头寸限制？？？？？？？
