Bresenham’s-Algorithm

Question 1
Consider the Bresenham's line generation algorithm for a line with gradient greater than one, current point (xi, yi) and decision parameter, di. The next point to be plotted (xi+1, yi+1) and updated decision parameter, di+1, for di < 0 are given as _______.
A
xi+1 = xi +1
yi+1 = yi
di+1 = di+ 2 dy
B
xi+1 = xi
yi+1 = yi +1
di+1 = di+ 2 dx
C
xi+1 = xi
yi+1 = yi +1
di+1 = di+ 2(dx -dy)
D
xi+1 = xi +1
yi+1 = yi +1
di+1 = di+ 2(dy -dx)
