   A program must read a user's height in meters (e.g., '1.75') and weight in kilograms (e.g., '70'), then print the BMI as a float. The developer writes: h = input(); w = input(); print(w / (h * h)). What is the result?

   • AIt prints the correct BMI because Python automatically converts strings to numbers.
   • BIt prints the string '70 / (1.75 * 1.75)'.
   • CA TypeError because w and h are strings.
   • DIt prints 22.857142857142858 because the strings are implicitly converted.
