All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.
That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If

is the component for state

, then you have

which means

. So the state vector is

Answer:
This is an ellipse.
Step-by-step explanation:

Applying the angle values in intervals of right angles (90°), the resulting set of values for z are:
