Hi there.

The answer is C point.

Explanation:

$- 4 + 3i + 6 - i \\ 2 + 2i$

Count the x-axis/Re 2 units from 0 then Im 2 units from 0 as we get C point.

$\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{}{ h},\stackrel{}{ k})\qquad \qquad 
radius=\stackrel{}{ r}\\\\
-------------------------------\\\\
(x-5)^2+y^2=81\implies (x-\stackrel{h}{5})^2+(y-\stackrel{k}{0})^2=\stackrel{r}{9^2}~~
\begin{cases}
center~(5,0)\\
radius=9
\end{cases}$
