An E. coli F(+) cell
Phantasy [73]

Answer:

The correct answer will be option- C.

Explanation:

The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.

These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.

Thus, option- C is the correct answer.
