let A,B,C be three sets of complex number such that A={z:|z+1|<=2+Re(z)},B={z:|z-1|>=1} and C={z:|z-1| >=1} ----- |z+1| i) The no. Of point(s) having integral coordinates in the region A (intersection) B (intersection) C is A) 4. B) 5. C) 6. D) 10 ii) The real part of of the complex no. In the region A (intersection) B (intersection) C and havong max amplitude is )-1 B)-3/2 C)-1/2 D)-2
