Detailed explanation-1: -Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments.

Detailed explanation-2: -To cross-pollinate peas, pollen from the stamen of 1 plant is transferred to the stigma of another. Before the transfer, the anthers must be removed from the recipient plant to prevent self-pollination.

Detailed explanation-3: -Removal of anthers/stamens from the flower bud before the anther dehisces is referred to as emasculation.

Detailed explanation-4: -So, the correct answer is ‘Emasculation’

Detailed explanation-5: -To perform his experiments, how did Mendel prevent pea flowers from self-pollinating and control their cross-pollination? He cut away the pollen-bearing male parts of a flower and dusted that flower with pollen from another plant.
