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
