Assertion (A): For two attributes A and B, if (AB) > (A)(B)/N, they are positively associated. Reason (R): Positive association means they occur together more often than expected under independence. Choose the correct option:

A. A is true, R is false

B. A is false, R is true

C. Both A and R are true, and R is the correct explanation of A

D. Both A and R are true, but R is not the correct explanation of A

Answer: Option C
