This MCQ QUESTION FROM BASIC POWER ELECTRICAL ENGINEERING course.

just write for me the the correct answer.

The 3-phase power and line-to-line voltage ratings of the electric power system shown in the following
figure are as follows:
X= 9%
Z= 2 +j5 2
X= 10%
X= 8%
Generator G
160 kVA
22 KV
Line
22 KV
Transformer T
Motor M
200 kVA
22/0.5 KV
40 kVA
0.4 KV
Va
Line
M
On a 100-kVA base power and 22 kV base voltage at the generator side.
If the line current is equal to 0.01 - j 0.02 pu, then it is in amperes equal to:
O a. 48.4 - 196.8 A
O b. 220 - J440 A
O. 45.45 - j90.9 A
O d. 1000 - j2000 A
Oe.
2.2 - j4.4 A
O f.
220 + j440 A
O g. None of these answers is correct
