Correct option is A
• Micropropagation is a tissue culture technique used to produce large numbers of genetically identical and disease-free plants in a short period.
• It is especially important for vegetatively propagated crops that do not produce good seeds, such as banana, which is sterile and normally propagated by suckers.
• Using micropropagation, thousands of banana plantlets can be produced from a single explant, ensuring fast multiplication and uniform, disease-free planting material.
