Self-incompatibility in plants is a genetic mechanism that prevents self-pollination and promotes cross-pollination. It is a well-designed mechanism by which certain plants recognize and reject their own pollen, thus encouraging outbreeding. This mechanism ensures genetic diversity in plant populations by promoting the transfer of pollen from one plant to another, typically through the assistance of pollinators like insects, birds, or wind. Self-incompatibility helps to prevent inbreeding and maintain genetic variability within plant species, leading to healthier and more adaptable populations.

Option 2 is the correct answer.
