The command that compiles all the code in the book using a master makefile is make -f master.makefile. Option A, make all, would only compile the code in the current directory, not all the code in the book. Option B, compile everything, is not a valid make command. Option D, make book_code, would only compile the code for the specific book, not all the code in the book as the question asks. Therefore, the only correct option is C, which specifically points to the master makefile and compiles all the code in the book.
