When the human body temperature falls by about 2 – 3.5°f below the normal body temperature, the condition is known as A. Fever B. Hypothermia C. Hypermetropia D. Hyperthermia

Hypothermia is the condition in which body temperature falls below normal (about 37 °C / 98.6 °F), usually after long exposure to cold. Hyperthermia is the opposite (abnormally high temperature), and hypermetropia is long-sightedness, an eye defect.
