In his text he discussed the causes of spread, instances and scientific evidence of Cholera of its communication among different populations.
Hence, the correct answer is 'Option A and B'.
Cells contain a transforming factor summarizes the findings of Griffith.
<u>Explanation:</u>
Numerous experts assigned to the description of DNA as the genetic material. During the 1920s, Frederick Griffith obtained an outstanding invention. He was inquiring two separate forces of a bacterium, called R (rough) strain and S (smooth) strain. He infused the two strains into mice.
Griffith settled that the R-strain bacteria must have brought up a "transforming principle" from the heat-killed S bacteria, which enabled them to "transform" into smooth-coated bacteria and become injurious. He called this method transformation, as something was "transforming" the bacteria of one strain into another strain.
