A Correct answer
Explanation

Tissue culture allows horticulturists to produce thousands of genetically identical plantlets from a small piece of plant tissue in a controlled laboratory environment. This method is commercially valuable because it rapidly produces disease-free plants on a large scale, unlike slow natural selection or vegetative methods like budding and cutting that have limited scale.
