Answer 2

Cross-pollination is important for producing new varieties of plants, plants having better growth and the creation of more viable seeds.  

Answer: Option iv)  

Explanation:  

Cross-pollination is the process where plants of different variety breed with another to create a unique plant that has the genetic material from both the parents. The resultant plant shows characteristics of both the parent generation and therefore this method is often used to create new varieties of plants.
