Correct Option: B

AI Explanation

To copy a string into another, you can use the strcpy() function from the string.h library in C.

Let's go through each option to understand why it is correct or incorrect:

Option A) s2 = s1; - This option is incorrect because it assigns the memory address of s1 to s2, rather than copying the contents of s1 into s2.

Option B) strcpy(s2, s1); - This option is correct. The strcpy() function is used to copy the contents of one string (s1) into another string (s2). It takes two arguments: the destination string (s2) and the source string (s1).

Option C) s2 == s1; - This option is incorrect. The == operator is used to compare the memory addresses of two variables, not their contents.

Option D) all three are wrong - This option is incorrect because option B is correct.

Therefore, the correct answer is B) strcpy(s2, s1);. This option correctly copies the contents of s1 into s2 using the strcpy() function.
