Solution
The correct option is B Kappa particles
One of the most striking and spectacular cases of cytoplasmic inheritance occurs in paramecium aurelia. In 1938, T.M. Sonneborn reported that some strains contain kappa particles in the cytoplasm and are known as “Killers “. Kappa particles are about 2 μ x in diameter and contain DNA and protein.
Individuals not possessing Kappa particles are sensitive and are killed by a poison ‘paramecin’ which is secreted by Killer individuals. The secretion paramecin is harmless to the killers. The different killer strains have different means of killing their victims.
So, the correct answer is 'Kappa particles'.
