Solution
The correct option is A Meristem culture Meristematic cells are used to make virus-free banana. Generally, apical and axillary meristems are virus-free mostly as they are actively dividing and producing various structures like the leaves and flowers.
Bioremediation is the use of either naturally occurring or deliberately introduced micro-organisms to consume and break down environmental pollutants.
Somatic embryogenesis is an artificial process where the plant or the embryo is generated using isolated somatic cells.
Micro-propagation is the practice of rapidly multiplying stock plant material to produce many progeny plants using the method of tissue culture. It can employ use of any tissue.
Meristem culture is specific to the requirement of the question and is generally used for virus-free preparations.
