The answer is B or option 2 because this is a true statement and none of the other ones work. To solve these types of problems for future reference, just use the process of elimination for each answer and you will find the correct answer every time. Hope This Helps and God Bless!
The error is that 9 shouldnt be written as nine it should be written as 3x3 or 3^2. So the answer should be 2^3 x 3^2 because 9 can be divided into even more prime factors of 72.
