Which of the following describes code wrapping?

Using API hooks to inject code into a running process describes process injection or DLL injection, a separate technique for hijacking a live process's execution context.

Code wrapping refers to the practice of embedding one language's script inside another program by treating it as a variable or callable object, allowing the host program (C) to execute the wrapped script (Ruby). This enables cross-language execution and is distinct from injection or tunneling techniques because the wrapped code is part of the program's own variable scope.

Tunneling encoded commands inside DNS query packets describes DNS tunneling, a covert channel technique used for data exfiltration or command-and-control, not code wrapping.

Packing an executable into a compressed file describes executable packing or crypting, a malware obfuscation technique used to evade antivirus detection.
