  2. BMicro-injection
  3. CHeat shock method
  4. DUse of disarmed Agrobacterium vectors

Correct answer

B. Micro-injection

Step-by-step solution

In the micro-injection technique, recombinant DNA is directly injected into the nucleus of an animal cell. Biolistics or gene gun method is primarily used to introduce DNA into plant cells. The heat shock method is used to make bacterial cells competent to take up recombinant DNA. Disarmed Agrobacterium vectors are used to deliver genes of interest into plant cells.
