Answer: Option A

First time cytoplasmic genetic male sterility is used in Onion.
Background. Joseph Gottlieb Kölreuter was the first to document male sterility in plants. In the 18^th century, he reported on anther abortion within species and specific hybrids. It is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions.
Cytoplasmic male-sterility (CMS) has been used in F1 hybrid seed production in onion (Allium cepa L.). Two types of CMS (CMS-S and CMS-T) have been reported in onions. Almost complete mitochondrial genome sequences of normal, CMS-T and CMS-S cytoplasm types have been obtained in previous studies.
