        DS:集合S中的元素都是正整数, N是S中的元素个数 

1)123456789/N 条件记不清啦 

2)123456789 prime factor 的个数=N 

 

这个怎么解啊？

不太明白

I think that it may be B if the questions asks your for N

Because you need a specific number for N.

1)123456789/N 条件记不清啦  ( you still don't know what is N)

2)123456789 prime factor 的个数=N (If you know 123...,you know the prime factor of this number for sure.Therefore you get N as a specific value for sure.)
