B Correct answer
Explanation

Male sterility is extremely useful in hybrid seed production because it prevents self-pollination, ensuring cross-pollination between desired parent lines. This technique allows breeders to produce large quantities of hybrid seeds efficiently and economically. It's not primarily used in pure line selection (which maintains homozygosity) or general crop improvement (which is broader in scope).
