Answer:
Option A.
Step-by-step explanation:
step 1
we know that
The equation of the solid line is

The solution is the shaded area above the solid line
so
The equation of the first inequality is

step 2
The equation of the dashed line is

The solution is the shaded area above the dashed line
so
The equation of the second inequality is

therefore
The system of inequalities could be


Y is the answer for four right angles
