Solution
The correct option is B all the offspring were tall
A pure line shows the stable trait inheritance due to continuous self-pollination.
The pea plant which was grown in nutrient deficient soil was pure line for the trait of being tall. Hence, the genotype of the plant was TT (homozygous dominant).
Nutrient deficiency in the soil resulted in the stunted growth of the plant, however, it did not interfere with the genotype of that plant.
When this plant was crossed with a dwarf plant, all the offspring were tall.
