Answer:
Transforming material would be the genetic material.
Explanation:
Griffith was performing the tests to know how bacteria cause pneumonia for which he selected two strains.
The R strain was avirulent but S bacteria was virulent which in one case when he heat killed the virulent bacteria and then injected them with the avirulent bacteria, he found that the avirulent bacteria that is R bacteria transformed into the virulent bacteria.
When he isolated the S bacteria, the R bacteria were still able to cause the disease in mice which shows that the bacteria were transformed permanently and since the disease-causing ability is passed on to the generations, therefore, the disease-causing factor is present on the hereditary material or the transforming material is the hereditary material.
The correct option is D.
