The factors of 80 are $\(1,2,4,5,8,10,16,20,40\)$, and 80 .
So, the factors of 80 greater than $\(\sqrt{80}\)$ are $\(10,16,20,40\)$, and 80 .
Therefore, Column A is 5 .
The factors of 90 are $\(1,2,3,5,6,9,10,15,18,30,45\)$, and 90 .
So, the factors of 90 greater than $\(\sqrt{90}\)$ are $\(10,15,18,30,45\)$, and 90 .
Therefore, Column $\(\mathrm{B}=6\)$.
Hence, Column B $\(>\)$ Column A.
Thus, the correct answer is $\(B\)$.
So, the factors of 80 greater than $\(\sqrt{80}\)$ are $\(10,16,20,40\)$, and 80 .
Therefore, Column A is 5 .
The factors of 90 are $\(1,2,3,5,6,9,10,15,18,30,45\)$, and 90 .
