Answer: Option B

A cybrid is a hybrid formed by cell division.
Cybrids are eukaryotic cell lines produced by the fusion of a cell that serves as a nuclear donor, and a cytoplast from a different source, serving as a mitochondrial donor.
Cybrids are produced by combining cytoplasm from nucleated cells with non-nucleated cells or cytoplasts. The nucleated cell can be unaltered or could have undergone depletion of endogenous mtDNA before cytoplasmic mixing.
