Quizplus · Accepted Answer

LD₅₀ is the lethal dose required to kill 50% of the test population (LD50) by oral administration in rats weighing 1 kg. We need to find the lethal dose required to kill 50% of the test population for rats with a body mass of 0.500 kg. We can use the following formula: LD50 (mg/kg) x body weight (kg) = LD50 for the given body weight Substituting the values given, LD50 for the given body weight = 200 mg/kg x 0.500 kg = 100 mg Therefore, the lethal dose required to kill 50% of the test population for rats with a body mass of 0.500 kg is 100 mg. The correct answer is C.
