   A developer is creating a function that converts a temperature from Celsius to Fahrenheit. The formula is `F = (C * 9/5) + 32`. The function takes a Celsius value as input. What is the correct way to define and call this function?

   • A`function convertToFahrenheit() { return (25 * 9/5) + 32; }` and call it with `convertToFahrenheit(25)`.
   • B`function convertToFahrenheit(celsius) { return (celsius * 9/5) + 32; }` and call it with `convertToFahrenheit(25)`.
   • C`function convertToFahrenheit(celsius) { print((celsius * 9/5) + 32); }` and call it with `convertToFahrenheit(25)`.
   • D`function convertToFahrenheit(fahrenheit) { return (fahrenheit * 9/5) + 32; }` and call it with `convertToFahrenheit(25)`.
