Answer:

B. Each parent only passes on one-half of its hereditary factors to each offspring.

Explanation:

Pea plants have both male and female reproductive organs.  As a result, they can either self-pollinate themselves or cross-pollinate with another plant.  In Mendel's experiments, he was able to cross-pollinate purebred plants with particular traits and observe the outcome over many generations.  

As a little fun fact; as we know, both human parents have 46 chromosomes, and when reproduction occurs, they both give half of their chromosomes (23) to their offspring!
B. Each parent only passé down one half it’s hereditary factors to offspring
