A conditional relative frequency table is generated by column from a set of data. The conditional relative frequencies of the two categorical variables are then compared.

A
An association cannot be determined between the categorical variables because the relative frequencies are not similar in value.
B
There is likely an association between the categorical variables because the relative frequencies are not similar in value.
C
An association cannot be determined between the categorical variables because the sum of the relative frequencies is 1.0.
D
There is likely an association between the categorical variables because the sum of the relative frequencies is 1.0.
