The terms ‘micro-injection’, ‘biolistics’ and ‘disarmed pathogen vector’ are related to

The correct option is B Recombinant DNA technology
Gene transfer process
Gene transfer is the process of introducing foreign gene or recombinant DNA into the host cell. There are various gene transfer processes depending on the host. Examples include disarmed pathogen vectors, biolistics, micro-injection etc.

Bioterrorism
Bioterrorism is the intentional release of highly virulent pathogens like bacteria, viruses etc, that cause disease or kill people.

Biosafety
Biosafety involves the measures taken for safe handling of the pathogenic microorganisms taken up in medical and research facilities.

Integrated pest management
Integrated pest management involves the measures to remove the pests and stop their growth in the surrounding environment by using the biological (natural predators of pests), chemical and cultural methods.

Recombinant DNA technology
Recombinant DNA technology refers to techniques that involve the modification of genetic material (the vector) by the insertion of a gene of choice thus forming a recombinant DNA. This DNA is then delivered into the host cell so that multiple copies can be made. ‘Microinjection’, ‘biolistics’ and ‘disarmed pathogen vectors’ are methods used to deliver genes to the host cells.

Final answer
d. Recombinant DNA technology.
