A Bank uses encryption key generating program that uses two numbers of the current date as its source - the number denoting the month (e.g. it is Aug then number is 8) and the date (e.g. today is 15th of the month). The encryption key is the hardest to crack if the two numbers are relatively prime. Password hackers run Trojan programs to try to get the data on credit cards which are stored using this encryption program. Which month is the most vulnerable to Trojan attacks out of the given option?
