The answer is the second one (conjugation): the transfer of DNA from one bacterium to another using a hollow bridge that formed between the two bacteria.

Explanation for each option:

  1. Transformation: This involves the uptake of naked DNA from the environment by a bacterium. It does not involve a direct connection between two bacteria.
  2. Conjugation: This is the correct answer. Conjugation involves the transfer of DNA from one bacterium to another through a direct connection called a pilus or conjugation bridge.
  3. Transduction: This involves the transfer of DNA from one bacterium to another via a bacteriophage (a virus that infects bacteria). It does not involve a direct connection between the bacteria.

Summary: Conjugation is the process that involves the transfer of DNA from one bacterium to another using a hollow bridge that forms between the two bacteria.
