Which TABLES option(s) would be used to eliminate the

row and column counts and just see the frequencies and percents?

     A. norowcount nocolcount

     B. freq percent

     C. norow nocol

     D. nocounts

答案说选了C，有点费解，c选项不是不输出行百分比和列百分比吗，我感觉题目是输出要see the frequencies and percents的啊

The question is "Which TABLES option(s) would be used to eliminate the row and column counts and just see the frequencies and percents?"
So, it is quite clear

Need
row and column counts
frequencies and percents

FREQ without options it will generate
Frequency
Percent
Row Pct
Col Pct

need remove Row and Col pct

then the answer is C

By the way, A, B, D are invalid options also.

题目是说要去除行与列的统计数据，仅留计数和整体百分比，所以就是norow nocol这个option加上去咯

对的，题目要求是消除百分比
