Solution

The correct option is B Mitochondria, plastid and nucleus
Mitochondria and chloroplasts grow in a coordinated process that requires the contribution of two separate genetic systems. One in the organelle and one in the cell nucleus. Most of the proteins in these organelles are encoded by nuclear DNA, synthesized in the cytosol, and then imported individually into the organelle.
Hence B is correct option.
