(2) The mascots of the 2008 Beijing Olympic Games in China consist of 5 "Chinese Fuwa", named Beibei, Jingjing, Huanhuan, Yingying, and Nini. There are two sets of Fuwa of different sizes (a total of 10 Fuwa). From these two sets of Fuwa, any 5 Fuwa are selected, and the number of ways to select them such that exactly one is missing to form a complete set of "Olympic mascots" is ( ).
(A) 160 ways
(B) 320 ways
(C) 32 ways
(D) 120 ways
(2) $\mathrm{C}_{5}^{1} \cdot \mathrm{C}_{4}^{1} \cdot 2 \cdot 2 \cdot 2=160$. Therefore, the correct choice is $\mathrm{A}$.
