Control string is " ".

Escape sequence characters such as "\n" (newline character) etc.

Example printf ("hello \n world") ;.
it will display hello and then a new line then display world.

Hello.

World.

The control string used with printf for printing the o/p. Ex- %d. %c, %%f.

I think option A is correct let see example printf("hello \n world");

It will display hello and then new line then display world.

Syntax of printf () is :
printf ("Control String", arg1, arg2, …. , arg n) ;.

Explanation:

(1) The "Control String" specifies the field format in which data is to be printed on terminal.
(2) It consists of three types of items.

A. Characters (String) that will be printed on the screen as they appear.
B. Format specifications that define the output format for display of each item. (like %d %f %c %ld %u etc).
C. Escape sequence characters such as "\n" (new line character) etc.

Newline character is \n which is included between ' '.
Like as '\n'.

Control string is " "...
