Best answer
Right option is (a) Alive

The explanation is: The mouse fed with the S-strain from the Staphylococcus pneumoniae, happens to naturally die. This is on an account that the S-strains are virulent. Under such conditions, the mouse will not be able to survive. But, when the heat killed S-strains from Staphylococcus pneumoniae are injected into the mouse, it will live.
