The approximate LD50 of the least toxic substance will be 130 mg/Kg.
- The dose necessary to cause the death of 50% of a population under test after a predetermined test period is known as the LD50 value for a drug.
- Commonly used as a broad indicator of a substance's acute toxicity are LD50 values.
- Greater toxicity is indicated by a lower LD50. A low LD50 of 500 mg/kg or less implies severe toxicity.
- Moderate toxicity is indicated by an LD50 of 500 to 1,000 mg/kg. A modest toxicity level of 1,000 to 2,000 mg/kg is indicated.
- The species is especially vulnerable to the poison if the LD50 is low. The lethal dose (LD50) of a specific poison might change significantly between several animal species.
- Thus out of all the options, LD50 130 mg/kg will have the lowest toxicity and 20 mg/kg will be the highest.

Answer:
Gene Therapy
Explanation:
The introduction is through the DNA encapsulated in a virus it is gene therapy—Not pharmacogenetics. Genesplicing are usually use his mRNA.
It’s A the luteinizing hormone
The root system, the roots can store energy, anchor the plant to the ground and other surfaces, and they also adsorb and "drink" nutrients and vitamins from the soil. Remember to check yourself.
