Griffith co-injected the heat-killed S and live R strains of Pneumococcus bacterium into the mice and much to his surprise the mice developed pneumonia and died. He concluded that:
| I: | Live R was transformed into Live S strain as he was able to isolate Live S strain from the blood of the infected mice. |
| II: | Bacterial transformation is a stable and heritable change as the culture of bacteria isolated from dead mice was unable to infect other mice. |
| 1. | Both I and II are correct |
| 2. | Only I is correct |
| 3. | Only II is correct |
| 4. | Both I and II are incorrect |
