The function that returns the length of a C-string (sequence of characters terminated by a null character) is the standard library function `strlen`. This function takes a pointer to a C-string as an argument and returns the number of characters in the string, excluding the null terminator. Option A, numchar, is not a standard library function for finding the length of a string. Option B, strlength, is similar to strlen but not a standard library function. Option D, countstring, is not a standard library function for finding the length of a string. Option E, none of these, is not the correct answer as there is at least one correct option.
