Let m and n (m ≠ 0) be constants. If in the positive proportional function y = KX, the independent variable x increases m and the corresponding function y increases n, then the value of K is () A. k＝nmB. k＝mnC. k＝−nmD. k＝−mn

From the meaning of the title, we get y = KX, y + n = K (x + m) 2, 2 - 1, n = km, and K = nm
