Correct answer: D
Explanation
All the above is correct because vertical resistance can be described by race-specific, oligogenic, and qualitative traits. Option A is incorrect because it is only one possible description. Option B is incorrect because it describes a genetic pattern, not necessarily the synonym for vertical resistance. Option C is incorrect because it is another descriptive term that might apply but isn't the comprehensive answer.
