Answer:
Option B, The mouse lived.
Explanation:
In Griffith's experiments three major observations were made -
a) Injecting the mice with S - strain bacteria - The S - strain bacteria's were infected bacteria's and hence when these S -bacteria's were injected into the mice ,they were killed due to infection.
b) Injecting with R -strain harmless bacteria - These being harmless did not affected the mice and hence they remained healthy and alive
c) Injecting heated S -strain into R -strain infected mice - These mice also developed the disease due to virulent remains of heated S -strain affecting the R -strain.
Hence, option B is correct
