A) A circle
B) A straight line
C) A parabola
D) None of these
Correct Answer: B
Solution :
Equation \[\overline{b}z+b\overline{z}=c\] Putting \[z=x+iy,b={{b}_{1}}+i{{b}_{2}}\] where \[x,y,\,\,{{b}_{1}},{{b}_{2}}\] are real, then the given equation become \[({{b}_{1}}-i{{b}_{2}})(x+iy)+({{b}_{1}}+i{{b}_{2}})(x-iy)=c\] or \[2{{b}_{1}}x+2{{b}_{2}}y=c\] Which is equation of a straight line.
