$$
\sqrt[5]{(-4)^{5}}-(-5)^{2}-5+\sqrt[4]{(-43)^{4}}-\left(-3^{2}\right)
$$

The result is
(A) 0.
(B) -68.
(C) 18.
(D) -86.
(China Beijing Junior High School Mathematics Competition, 1982)
$$
\text { [Solution] } \begin{aligned}
& \sqrt[5]{(-4)^{5}}-(-5)^{2}-5+\sqrt[4]{(-43)^{4}}-\left(-3^{2}\right) \\
= & (-4)-25-5+43+9 \\
= & 18 .
\end{aligned}
$$

Therefore, the correct choice is $(C)$.
