Answer:
<h2>Hence the second option is the correct answer</h2>
Step-by-step explanation:
In this problem we are required to factor out the given terms as stated in the expression, what is obtainable is that we look for terms(greatest terms) that are common to all the terms in the expression and factor it out.
here is a way to do it
given the following expression

From the expression above we can see that 3 is common to all the terms of the expression so that we have

hence the second option is the correct answer
