4 Both \(\mathrm{S}\) and \({\rm{R}}\) strain are virulent
Explanation:
Streptococcus pneumoniae bacteria on culture plate produce smooth shiny colonies (S) while others produce rough colonies(R). S strain bacteria have mucous coat while \(\mathrm{R}\) does not. S strain are virulent and \(\mathrm{R}\) strain does not develop pneumonia.

Select the correct statement
1 \({\rm{R}}\) strain bacteria has a mucous coat
2 \(\mathrm{S}\) strain is virulent
3 \({\rm{R}}\) strain is virulent
4 Both \(\mathrm{S}\) and \({\rm{R}}\) strain are virulent
Explanation:
Streptococcus pneumoniae bacteria on culture plate produce smooth shiny colonies (S) while others produce rough colonies(R). S strain bacteria have mucous coat while \(\mathrm{R}\) does not. S strain are virulent and \(\mathrm{R}\) strain does not develop pneumonia.
