This question is a bit of a pit stop on the road to exam success. I'm going with B) Corrosion/Erosion - can't go wrong with a good ol' combo answer!

Erosion, huh? I don't know, the 'directional pattern' part makes me think this is more about corrosion. I'll play it safe and choose B) Corrosion/Erosion.

Hmm, this seems like a straightforward corrosion question. I'm going to go with B) Corrosion/Erosion - it fits the description of the localized losses with a directional pattern.
