C Correct answer
Explanation

In PL/SQL packages, procedures must be declared before they can be called by other procedures in the same package specification or body. If procedure B calls procedure C, and C is defined after B in the package body without a forward declaration, the compiler cannot resolve the reference to C when compiling B.
