Best answer
Right choice is (c) meta-characters

The best explanation: In Shell’s interpretive cycle, the shell first issues a prompt and waits for the user to enter the command. After the command is entered, the shell scans the command line for meta-characters and expands the abbreviations (like the * in rm*) to recreate a simplified command line.
