Consider the following method, which takes as input a temperature in degrees Fahrenheit and returns the corresponding temperature in degrees Celsius.
public double fahrenheitToCelsius(double f)

double c = (f - 32) * 5 / 9;
return c;

Assume that each of the following code segments appears in a method in the same class as fahrenheitToCelsius. Which of the following code segments prints the temperature in degrees Celsius that corresponds to 32 degrees Fahrenheit?
1) System.out.println(fahrenheitToCelsius(32));
2) System.out.println(fahrenheitToCelsius(0));
3) System.out.println(fahrenheitToCelsius(100));
4) System.out.println(fahrenheitToCelsius(-40));
