Solution

The correct option is B Similar phenotype
A pure line is created by breeding the same plant many times over through self-pollination or selfing, so as to create many clones with the same genetic material. The phenotypic differences (variation) within a pure line is environmental and therefore non heritable, so phenotype is not exactly same for all plants. So, all plants that have a pure line have the same genotype but similar phenotypes.
