How many pixels in an image have a red component whose value is greater than or equal to one number and less than or equal to a second number?

Suppose you were to write a function to calculate this value. Which one of the following options is the best choice for the parameters for this function?

Option 1:

Three parameters: 1) filename - the name of the file for the image 2) low - representing the lowest red value and 3) high - representing the highest red value in the range.

Option 2:

Four parameters: 1) filename - the name of the file for the image 2) low - representing the lowest red value, 3) high - representing the highest red value in the range, and 4) pixel - representing a pixel.

Option 3:

Five parameters: 1) filename - the name of the file for the image 2) low - representing the lowest red value, 3) high - representing the highest red value in the range, 4) height - representing the height of the image, and 5) width - representing the width of the image.

Option 4:

Three parameters: 1) filename - the name of the file for the image 2) height - representing the height of the image, and 3) width - representing the width of the image.
