The Oral LD50 (lethal dose for 50% of the population) is a standard measure used to assess the toxicity of substances, indicating the dose that can cause death in half of a tested population. For mice, the documented Oral LD50 is approximately 96 mg/kg. This value varies slightly depending on the substance being tested, but in the context of this question, the answer reflects a typical figure found in toxicological studies.

Choosing this option aligns with toxicology references that provide standard metrics for understanding the acute toxicity of chemicals in laboratory settings. Other values listed may come from different sources or specific substances, but they do not represent the general reference figure for the LD50 in mice that is widely recognized in scientific literature. Hence, the indication of 96 mg/kg serves as a critical benchmark for assessing risks associated with chemical ingestion in laboratory mice.
