The acute angle between two straight lines passing through the point `M(-6,-8)` and the points in which the line segment `2x+y+10=0` enclosed between the co-ordinate axes is divided in the ratio 1:2:2 in the direction from the point of its intersection with the x-axis to the point of intersection with the y-axis is: `pi/3` (b) `pi/4` (c) `pi/6` (d) `pi/(12)`
