Best answer
Correct answer is (c) read

The best explanation: The standard C library offers a set of separate functions to read a block of data. For example, to read a block of data fread is used, for reading a line fgets is used and for reading a character fgetc is used. All these functions invoke the system call -read, which is available for reading input.
