What visual defect can be caused by cambium miners in cherry wood?

Explanation:
Cambium miners damage the living tissue right at the cambial zone, tunneling through parenchyma cells as they feed. In cherry wood this results in galleries located in the cambial region, composed of damaged parenchyma tissue and the insects’ frass. That combination—tunnel networks in the cambial area filled with frass and disrupted cells—is the characteristic visual defect produced by cambium mining. The other options describe problems that come from mineral deposits, resin exudation, or growth-related grain distortion, which are unrelated to cambial tunneling.
