Answer: Option A
Solution(By Examveda Team)
The male sterility controlled by cytoplasmic genes and transmitted only through the female parent is called Cytoplasmic male sterility.Cytoplasmic male sterility is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions.
Male sterility is the failure of plants to produce functional anthers, pollen, or male gametes.
When nuclear restoration of fertility genes is available for a CMS system in any crop, it is cytoplasmic–genetic male sterility; the sterility is manifested by the influence of both nuclear and cytoplasmic genes.
