Solution

The correct option is B Bacterium
The experiment done by Meselson and Stahl demonstrated that DNA replication is semi-conservative, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. This was proved by CsCl density gradient centrifugation using DNA of E.coli, abacterium.
