The correct answer is: D. All of the above

A string is a sequence of characters. In C, a string can be assigned to a variable of type char or string. The conversion specification %s is used to read a string from the standard input.

Here are some examples of how to assign a string to a variable:

char str[] = "Hello, world!";
string str2 = "Hello, world!";

Here is an example of how to read a string from the standard input:

char str[100];
scanf("%s", str);

The %s conversion specification tells the compiler to read a string from the standard input and store it in the variable str. The 100 in the char str[100] declaration tells the compiler to allocate enough space for 100 characters.

I hope this helps!
