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.

Aha, I see what they're getting at. The keyword 'pits' makes me think corrosion is definitely involved here. I'll go with D) Both A and B.

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.
