Answer:

B.) -1/3

Step-by-step explanation:

According to the rational root theorem, rational roots will be of the form ...

±(divisor of the constant)/(divisor of the leading coefficient)

= ±(one of {1, 2, 3, 4, 6, 12})/(one of {1, 2, 4})

You will note that 3 is not among the possible denominators, hence -1/3 is not a possible rational root.

the answer is b cause its is correct
