Step-by-step solution

Statement (I) is correct: To sustain animal visits, flowers provide rewards such as nectar and pollen grains. Statement (II) is correct: In some species, such as Amorphophallus, the floral reward is providing a safe place to lay eggs. Statement (III) is incorrect: Pollen grains in animal-pollinated flowers are generally sticky, allowing them to adhere to the pollinator's body.
