what is the best choice for the header line of a function that converts kilometers to miles?\nvoid…

Brief Explanations:

The function is meant to convert kilometers to miles. It should take the input of kilometers (a single value representing distance in km) and return the equivalent distance in miles. The function should have a single - input parameter for kilometers and a return type of float (since the conversion results in a floating - point value). The first option has a void return type which is incorrect as it won't return the converted value. The second option has two parameters which is wrong as only the kilometers value needs to be input for conversion. The third option is for converting miles to kilometers. The fourth option has the correct return type (float) and takes a single float parameter for kilometers which is appropriate for the conversion task.

Answer:

float Kilo_to_Miles (float Kilometers)
