Answer 1

Answer:

C. Pili

Explanation:

Conjugation:

• Conjugation is the transfer of genetic material between two bacteria. It is referred to as horizontal gene transfer as it occurs through the formation of a horizontal connection or a pilus.
• Conjugation occurs when the donor bacterium, containing the fertility factor (F factor; it is the gene required for pilus formation) initiates pilus formation.
• This tube-like structure then joins the two bacteria and transfer of genetic material occurs.
• Plasmids containing antibiotic resistance genes are also transferred in this manner.
