Normal human body temperature98.6°F corresponds to ?

The correct answer is 37°C because converting 98.6 degrees from the Fahrenheit scale to the Celsius scale results in exactly 37 degrees.

• Step 1 (Conversion Formula): To translate temperatures from Fahrenheit (°F) to Celsius (°C), use the standard mathematical formula: °C = (°F - 32) × 5/9.
• Step 2 (The Calculation): Substituting 98.6 into the equation: 98.6 - 32 = 66.6. Next, multiply 66.6 by 5/9: 66.6 × 5 = 333, and 333 / 9 = 37. This proves that 98.6°F matches 37°C precisely.
• Incorrect Options:
  • 55°C is incorrect because this high of a temperature would be instantly fatal, far exceeding the boiling ranges of organic proteins.
  • 42°C is incorrect because 42°C represents a state of extreme, life-threatening hyperpyrexia fever in medical science.
  • None of these is incorrect because option 3 shows the exact mathematical match.
