Solution

The correct option is B
Fruit softening

Polygalacturonase is expressed in tomato only during the ripening stage of fruit development. PG becomes abundant during ripening and has a major role in cell wall degradation. PG helps degrade pectin, which is abundant in fruits. This helps in softening the fruits.
