Solution

Answer: Option B

Solution:

Pure line selection is used to improve the self-pollinated crop.
Pure-line selection involves selecting and breeding progeny from superior organisms for several generations until a pure line of organisms with only the desired characteristics has been established.
In pure-line selection, a large number of plants are selected from a self-pollinated crop and are harvested individually; individual plant progenies from them are evaluated, and the best progeny is released as a pure-line variety.
