Question 15 1 pts Consider the following program segment: char string1[50], string2[50]; int i; char ch; scanf("%s%s", stringi, string2); 1 = strlen(string1) + strlen(string); /* Add up the lengths of both strings */ ch = string1[0]; /* Store the first character of string1 */ stringi = string2; /* Take a copy of string2 and store it in string1 */ if (strcmp(stringi, string2) == 0) /* If stringl is identical to string2 */ Assume that relevant #include statements and int main(void) have been declared. Suppose the user enters "Hello" into string1. Which of the following would contain the letter 'o' ? A. string1[4] B. string1[5] C. string1[48] D. string1[49]
