Intraspecific cross-pollination is

Concept: As it includes pollinating plants of the same species, intraspecific cross-pollination is allogamy or pollination within the same species. 

• With the aid of agents like an animal or the wind, it permits fertilization and the creation of seeds. 
• Cross-pollination has the benefit of allowing the development of plants with a genetic variation that can aid in their survival. In contrast to self-pollination, cross-pollination results in the production of new varieties (hybrids). 
• Plants are given hybrid vigor, which strengthens them and accelerates evolution.

Hence, option A is the correct answer.
