Which type of icing is identified by K1b?

Explanation:
Carburetor icing, also called induction icing, is the icing type identified by K1b. This form occurs when moist air in the induction system cools and ice forms in the carburetor throat or venturi, restricting airflow and causing engine roughness or loss of power. K1b specifically points to this induction/carburetor icing as a recognized category. The other options describe different icing scenarios not grouped under K1b: icing in the fuel line involves the fuel system, exhaust icing isn’t the standard induction-icing category, and “induction icing only” is too narrow because carburetor icing and induction icing are considered together.
