(C) Let the $y$-axis divide the line segment joining $A(-3, -4)$ and $B(1, -2)$ in the ratio $k : 1$ at point $P(0, y)$.Using the section formula,the $x$-coordinate of point $P$ is given by:$x = \frac{m x_2 + n x_1}{m + n}$Since the point lies on the $y$-axis,its $x$-coordinate is $0$:$0 = \frac{k(1) + 1(-3)}{k + 1}$$0 = k - 3$$k = 3$Therefore,the required ratio is $3 : 1$.
