Best answer
Right choice is (a) True

To explain: A wildcard is a special character which can be used as a substitute for any of a class of characters, which increases the flexibility and efficiency of searching and replacing. For example, to remove all the files with a filename starting with ‘chap’ prefix, we can use the command rm chap*. Here * is used as a wildcard for matching all filenames starting with ‘chap’.
