Answer: FIRST OPTION.
Step-by-step explanation:
 For this exercise it is important to remember a property called "Quotient of Powers property".
  By definition the Quotient of Powers property states the following:
 
 You can observe the division of  and
 and  . Since both have the same base "a" , you must rewrite the base and subtract the exponents "m" and "n".
. Since both have the same base "a" , you must rewrite the base and subtract the exponents "m" and "n".
 
 In this case, you have the following expression given in the exercise:
 
 Then, you need to apply the Quotient of Powers property rewriting the base 4 and subtracting the exponents 12 and 5.
 Therefore, you get the following result:
 
 You can notice that it matches with the first option.
