Which of a to d is a quadrantal angle
An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.
Such angles (in degrees) are: 90, 180, 270, etc.
So, we have:

[Convert to degrees]


Hence:
is a quadrantal angle
<em>The other options are not.</em>
Step-by-step explanation:
x+x+x+x+2.5(2)+3(2)=x+x+2.5+3(3)
4x+5+6=2x+2.5+9
4x+11=2x+11.5
-11 -11
4x=2x+0.5
-2x -2x
2x=0.5
x=0.25
