A technology for achieving eugenic aims?

Explanation

The correct answer is cloning. Cloning is a technology that can be used to achieve eugenic aims by replicating organisms with desirable traits to create genetically identical copies. It directly manipulates genetic material to ensure specific hereditary outcomes, which aligns with the concept of eugenics. The hydroponic culture technique is focused on plant growth without soil and does not involve genetic manipulation. Bioremediation involves using organisms to clean environmental pollutants and is unrelated to genetic goals. Tissue culture technique is used for growing cells in artificial conditions, often for research, and is not primarily used for eugenic purposes.
