Abacterium that is transformed: select one:
a. will probably die within 48 hours
b. cannot form a conjugation pilus
c. if injected, it always will result in the death of a mouse
d. has acquired naked dna from the environment

d. has acquired naked DNA from the environment

Explanation:

Bacterial transformation is a process whereby a living bacterium takes up pieces of DNA from the environment and the foreign DNA becomes incorporated into the genome of the bacterium thereby 'transforming' it genetically.

A transformed bacterium does not necessarily die within 48 hours, all other factors being considered.

Transformation does not hinder a bacterium from forming conjugation pilus.

Transformation does not always make a bacterium to be lethal to mouse. It depends on the gene present in the foreign DNA.
