Best answer
Right option is (a) Fin focus of laser light is used

Best explanation: Laser-induced transfection is the use of a brief pulse of a focused laser beam. Here, DNA is mixed with the cells present in the culture. Then a fine focus of laser beam is passed on the cell surface which will form a small pore that will be sufficient for DNA uptake into the cells.
