$11 \square A B C D$ 中, 点 $A 、 B 、 C$ 分别对应复数 $2+i, 4+3 i, 3+5 i$, 则点 $D$ 对应的复数是
A. $3-i$
B. $1+3 i$
C. $5+7 i$
D. $D. 9+9 i$

In the quadrilateral $11 \square A B C D$, points $A$, $B$, and $C$ correspond to the complex numbers $2+i$, $4+3i$, and $3+5i$, respectively. The complex number corresponding to point $D$ is
A. $3-i$
B. $1+3i$
C. $5+7i$
D. $9+9i$
11 B. $z_{D}=z_{A}-z_{B}+z_{C}=(2+i)-(4+3 i)+(3+5 i)=1+3 i$.
