Afilling the line from its two end points towards the centre
Busing only integer additions and a decision parameter to choose the next pixel
Csolving the line equation for every pixel with a multiplication
Dtaking unit steps along the axis of greater change and adding the slope to compute the other coordinate

Correct answer: D

Explanation

DDA increments the major axis by one pixel at each step and adds the slope (a floating-point value) to the other coordinate, rounding it to find the pixel.
