Answer #1

ans is b that is transformation.

transformation is the genetic alteration of a cell results the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane. For this, the recipient bacteria must be in a state of competence, which might occur in nature as a time-limited response to environmental conditions such as starvation and cell density, and may also be induced in a laboratory.

Transformation is one of three processes for horizontal gene transfer, in which exogenous genetic material passes from one bacterium to another, the other two being conjugation and transduction. In transformation, the genetic material passes through the intervening medium, and uptake is completely dependent on the recipient bacterium.
