X≥ 0                             ...[1]
X2 ≥ 0                             ...[2]
XX≤ 10                    ...[3]
2X+ 2X 22                 ...[4]


Now the equation [4] can be written as
X
+ X≥ 11                     ...[5]
Now equation [3] and [5] cannot hold true together since X
≥ 0 and X2 ≥ 0.
Hence system of inequalities can never be satisfied.
Hence Answer A)0
