✔ 最佳答案
答案應是A 因為題目指seed dispersal 而不是seed formation
所以單純的dispersal不涉及genetic variation
因此statement (3) 是錯誤的

I found the explanation in a Pastpaper solution book, it says that seeds can be formed by self-pollination ,which doesn't have much genetic variations.
However, I think the best answer can also be a suitable explanation.
