Barry is making a program to process user birthdays. The program uses the following procedure for string slicing: Name Description SUBSTRING (string, startPos, numChars) Returns a substring of string starting at startPos of length numChars. The first character in the string is at position 1. His program starts with this line of code: userBday ← "03/31/1984" Which of these lines of code displays the month ("03")?

DISPLAY (SUBSTRING (userBday, 1, 2))
