问题如下：
About the leverage ratio, which of the following statements is inaccurate?
I. It is equal to tier 1 capital divided by on-and-off-balance sheet items and exposures.
II. It allows banks to lend nearly 33 times their capital.
III. It's nonrisk-based and it is a supplement to risk-based capital standards.
选项：
A.All of them.
B.I and III.
C.only II.
D.Neither of them.
解释：
D is correct.
考点：the leverage ratio
解析：
I是杠杆比率的定义，正确。
II和III是杠杆比率的性质，杠杆比率是non-risk based，均正确。
leverage ratio是tier 1/total asset>=3%，近似那就应该是total asset<=33倍Tier 1 capital，解释和助教的解答不是把capital和Tier 1混为一谈了吗？
