Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria pili
Pili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
- they help bacterial cells to attach to surfaces
- they serve as channels for the transfer of genetic materials during conjugation
When genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.
