When comparing C-strings for equality, we should use the strcmp() function, which compares each character of the two strings and returns 0 if they are identical. So, the proper expression to use when comparing str1 and str2 for equality is strcmp(str1, str2) == 0. Choices A and B are assigning values and not comparing them for equality. Choice D is not a proper expression for comparing C-strings. Therefore, the best choice is C.
