Solution

The correct option is C Particle gun
The Particle bombardment device, also known as the gene gun, was developed to enable penetration of the cell wall so that genetic material containing a gene of interest can be transferred into the cell. The particle bombardment starts with coating tungsten or gold particles with plasmid DNA.
So, option C is the correct option.
