Solution

The correct option is B Male plant parts
Pure strains were obtained by firstly removing all the male parts (stamens) of the flower (emasculation) and then bagging emasculated flowers with a bag to prevent contamination of its stigma with unwanted pollen.
Emasculated flowers are then pollinated with pollens from required flower to obtain pure strains.
