Which consequence results when a glider's control surfaces experience ice accumulation during flight?

💡 Explanation

Icing increases the glider's weight and disrupts airflow, therefore the stall speed increases rapidly because of a lower lift coefficient caused by separated flow; rather than decreasing parasite drag or affecting engine operation, which gliders do not use.
