The experimental organism was Mouse and the experimental Bacteria is pneumococcus.

Answer 2

Griffith's experiment was used in 'Pneumococcus'.

Option: (c)

Explanation:  

• Griffith used mice and Pneumococcus to study this experiment on transformation. He first used a virulent strain on the mice and the mice died.  

• Then the he used avirulent strain, the mice was living. Then he used virulent dead Pneumococcus and found that the mice was live.  

• Finally he used avirulent with dead virulent bacteria which he injected on a mice and to his surprise found that still the mouse died.  

• He came to a conclusion that there must be a factor which caused the change in the avirulent bacteria causing it to kill the mice.
