A. Froxiness

B. Druxiness

C. Callus

D. Burls

I have been asked this question in class test.

This interesting question is from Defects and Preservation of Timber topic in chapter Materials for Construction of Basic Civil Engineering

Right option is A. Froxiness

The best I can explain: Druxiness is indicated by white spots.  Callus is soft tissue that covers wound of a tree.  Burls are swelling on the surface of the tree.
