Answer:

The answer is "\bold{A \cap\ B=\phi}"

Explanation:

let

A=\{1,2,3\}\\\\B=\{4,5,6\}

A and B are disjoint sets and they are not an empty set  then:

A\cup\ B=\{1,2,3,4,5,6\} \\\\A\cup\ B\neq 0

therefore if the intersection of the two non-empty sets is the empty set then its disjoint set, which is equal to \bold{A \cap\ B=\phi}.
