\]

**Explanation:** For all sets $A$, $B$, and $C$ within a universe $U$, prove the given equation or disprove it by finding a counterexample.

**Options:**
- Proven
- Disproven

This task involves exploring the properties of set difference and intersection to determine the validity of the given expression.
