Correct answer
C0.21 A from positive to negative terminal

Step-by-step explanation

  

-5i2-10i1+i2-2i2+20=0

-10i1-17i2+20=0

-10+4i1+10i1+i2=0

14i1+10i2+10=0

10i1+17i2=20→×10

14i1+10i2=10→17

-138i1=30

i1=-30138=-0.217

i1 is negative it means current flows from positive to negative terminal
