A Correct answer
Explanation

Xenogamy is the correct term for pollination between two different plants (cross-pollination). Geitonogamy is pollination between different flowers on the same plant. Cleistogamy refers to self-pollination without opening flowers. Dichogamy is the temporal separation of male and female reproductive phases in hermaphroditic flowers. The question asks about pollination between flowers on DIFFERENT plants, which matches xenogamy exactly.
