Answer 1

Correct choice is (a) fgets()

Easy explanation: The function fgets() will return a line from an open file. This stops returning on a new line, at the specified length, or at EOF, whichever comes first.  Its prototype is string fgets(resource handle [, int length]). If the optional length parameter is omitted, 1024 character is assumed.
