Correct answer: A
The strcmp() function compares two strings lexicographically, character by character, starting from the first position.
It compares the ASCII values of the characters at each position until it finds a difference or reaches the end of one string.
In this case, the first characters are 'w' from str1 and 'h' from str2.
Since 'w' has a higher ASCII value than 'h', the function returns a positive number.
The condition strcmp(str1, str2) > 0 evaluates to true, so the if block executes and prints "str1 is greater".
