Answer 1

Explanation:

Answer 2

(B) Male sterile plant

Hybridization in plants is defined as the process of removal of anthers in the plant without injuring the pistil. Hybridization is done in such plants which pollinate bisexual flowers along the pollen grains which helps in the process of pollination of the plant.

While in the case of a unisexual flower, emasculation has no validity because they do not form other varities of flowers during their hybridization.

Emasculation may be defined as a procedure for removal of stamens or killing the pollinating grain of flowers with the female reproductive organ remain untouched.

So, in this way we can say that emasculation is not required for plants with male sterile flowers.
