Detailed Solution

Statement I is correct. Even if a plant is infected with a virus, the apical meristem, which is the growing tip of a plant, is typically free of the virus. This is because the apical meristem contains actively dividing cells that are protected by layers of surrounding tissue, making it less susceptible to viral infection compared to other parts of the plant.
Statement II is also correct. The method of producing thousands of plants through tissue culture, where small pieces of plant tissue are cultured under sterile conditions to regenerate whole plants, is indeed called micropropagation. This technique allows for rapid multiplication of plants with desirable traits and is widely used in agriculture and horticulture.
