Concept:Cross-pollination mixes genetic material from different plants, producing stronger offspring and new varieties.
Explanation:Pollination is the transfer of pollen from the anther to the stigma.
In cross-pollination, pollen moves from one flower to the stigma of a flower on a different plant of the same species.
This introduces greater genetic variation.
Greater variation leads to healthier offspring and viable seeds.
It also helps form new varieties through genetic recombination.
Self-pollination, by contrast, limits genetic variety and may produce weaker offspring.
Therefore, the described benefits are linked to cross-pollination.
Answer:B. cross pollination
