Which condition can cause ADS data errors?

Explanation:
Air Data System relies on static pressure from the static ports (along with pitot pressure) to compute airspeed, altitude, and vertical speed. When the static ports are blocked, the ambient static pressure input becomes incorrect, so the calculations feeding the ADS become biased or erroneous. That directly leads to ADS data errors shown on the flight displays. Blocking the pitot tube would mainly affect indicated airspeed, not the broader set of air data values, and environmental noise on the cockpit microphone or a GPS outage don’t influence the air data inputs that drive ADS.
