11. The sequence $C_{1992}^{1}, 2 C_{1992}^{2}, \cdots, 1992 C_{1992}^{1992}$ has its maximum term as ( ).
A. $997 C_{1992}^{997}$
B. $998 C_{1992}^{998}$
C. $999 C_{1992}^{99}$
D. $1000 C_{192}^{1000}$
11. A. Since $k C_{1992}^{k}=1992 \cdot C_{1991}^{k-1}$, the original sequence is $1992 \cdot C_{1991}^{1}, 1992 \cdot C_{1991}^{2}, \cdots, 1992 \cdot C_{1991}^{1991}$, thus the middle two terms $1992 \cdot C_{1991}^{996}=1992 \cdot C_{1991}^{997}$ are equal and the largest, so the answer is A.
